(Updated--no, none of this post is true. They really are just thought experiments.)
Some thought experiments:
(1) In 2027, using powerful new microscopes, scientists identify a pathogen which is proven conclusively to be the cause of homosexual inclinations. The pathogen is non-communicable between humans, and infects hosts only through random atmospheric transmission unrelated to coughing, sneezing, fluid transfer, skin contact, proximity, et cetera. It is shown in trials to affect developing nervous systems, alter brain chemistry and personality, and result in various stages of attraction to the same sex. Biological research and carbon dating shows that it originated around 15,000 years ago, and has been spreading ever since. The initial discoveries were made by teams headed by atheist homosexual men and women, and corroborated by dozens of universities and private labs around the world. Further research shows that, once infected, a victim of the pathogen cannot be cured, because the initial exposure causes irreversible neurological effects. However, it is cheap to eliminate the pathogen entirely from the biosphere, preventing the infection of anyone else not already infected.
Is your moral stance:
(a) Now that we know it's caused by a pathogen, the pathogen must be entirely eliminated, so that it doesn't affect anyone anymore;
(b) The pathogen should be eliminated from an uncontrolled spread, but it should be carefully stored, so that parents can choose if they want to infect their child and raise her/him to be homosexual or bisexual;
(c) Parents should be prevented from making the choice to infect a child with homosexuality, but once a person reaches the age of majority, s/he should be able to decide whether or not to be infected and become homosexual;
(d) The pathogen should be distributed to everyone, so that everyone becomes equally homosexual (or bisexual);
(e) The pathogen should be studied further, then mutated into different varieties, so that, upon reaching the age of majority, people can choose whether to remain heterosexual, or to become homosexual, bisexual, ambisexual, pansexual, attracted to desired species of animals, or attracted to inanimate objects or situations of their choosing;
(f) The pathogen should be left alone, meaning that many people will be infected when they didn't choose to be, and that others will not be infected if they would have chosen to be.
Which one? Remember--the pathogen is non-communicable, so if it's controlled and stored for parental/personal use, there is no danger of accidentally infecting someone else. Even if the labs studying and storing the pathogen all blow away in tornadoes, they all have fail-safe mechanisms so completely perfect that there is zero danger of unwanted contamination. Assume a 100% secure storage system, and that only parents or adults who choose will be infected. Also assume that, if the pathogen is left alone, people won't know how to identify if they have it, and will be unable to emotionally develop with the knowledge that they are or aren't more or less likely to be a certain way, and many who do develop, and have the pathogen, will be bitter and miserable for the rest of their lives, wondering why they could choose to not get polio, but not choose to have their development remain unaffected by a different pathogen. "Don't we have control over our own bodies and sexual identities?" they ask those who choose (f). "How could you make that choice for us?"
(2A) In 2027, the skies turn red worldwide. Every single person on Earth slows their cars, lands their planes, anchors their boats, gets off their bicycles, and falls into a gentle sleep. In their sleep, everyone has the same vivid dream, and is at once aware that all other humans are simultaneously having the same dream. They all feel as though they are floating in a diaphanous mass in the street outside U.N. headquarters in New York.
A single light shines on the U.N. building, and a giant foot steps from the heavens onto the street out front. The foot and leg reduce in size, shrinking further and further, until a wise old man is standing there--a man as tall as the U.N. building. He is handsome, wearing a simple golden crown, has a long, full, white beard, and wears a plain toga and a pair of sandals. When he gestures, the Earth trembles, though no buildings fall.
"I am He Who Is," He says, in a voice that all humans hear in their native language, "and I have come to make some things clear."
He crosses his arms.
"Firstly, thou shalt not wear polyester. Other blended fabrics are acceptable, but all polyester must be burned immediately when you wake. Secondly, I am sick and tired of Islam. When you awaken, all who called themselves Muslims will be gone. I will also turn Mecca into a church with flying buttresses and stained glass windows. The windows will portray pictures of lambs, winged babies, and other thinks which I shalt find likable, and which you shalt find likable unto me. Moreover, your program of space exploration irritates me. It is not meant to be. All of your space-tools will disappear, and you will not make them again. Also, read the Bible more. I prefer the King James Version, which describes how I created existence. In fact, I hate all the other versions."
He shifts his feet and adjusts his toga.
"Lastly, it is really gross when men put their phalluses into other men's anuses. You will all stop doing that now, or when you die, I will torture those men forever. Everyone else will have a party with me where we sing holy songs about how wonderful I am, and are constantly in ecstasy. But anyone who does that gross penis-butt thing I mentioned, for any reason, will spend eternity being eaten by ants, and other creative things like getting stretched on the rack and whipped and boiled in lava, by this one friend of mine who really gets into that sort of thing. And it will never end for them. Don't ask why, and no, it's not about bacterial infections or promiscuity, so even if you do it with only a single partner ever, after an antibacterial enema and using six condoms every time, you will suffer.
"As for the rest of you, that particular thing is so gross, and gets me so mad, that I want you to kill anyone who does it. I said their blood shall be upon them, and I mean it. Kill them or I will assume you are condoning their behavior which is against me, and will send you to eternal torture along with them, but if you kill them, I will be very pleased with you. I am not even remotely joking. He Who Is sees all and knows all. And I forget nothing. I will cure Ebola and the common cold now to make things abundantly clear to you endlessly questioning children of mine. Now, awaken."
And everyone wakes up, amazed to find that everyone else has had the same dream. Over the next few days, people watch television constantly, discovering that Mecca has indeed been turned into a mid-18th century cathedral. All Muslims on the planet have vanished without a trace. The common cold and Ebola are eliminated, and not a single case is ever reported again, except by Richard Dawkins, who later confesses to faking the sniffles in an attempt to discredit his arch-nemesis. Billions of people insist that there was once a book called "The Qur'an," but no copies remain, either in paper form, on kindle, or on any computer database anywhere. All space exploration vehicles have vanished along with the Muslims and the Korans, and even though all the Americans remember that NASA existed, all its buildings and technology are gone. Remaining behind are billions of pictures of space shuttles and space stations, Hubble Telescope images, Mars Rover images, on websites and in textbooks, but all cellular satellites are gone, and all rocket scientists claim that they "can't remember" how to build anything or do the math.
Years of painstaking research reveal that all of the bearded old man's predictions have come true. It is beyond a doubt that this immensely powerful being is God. Richard Dawkins commits public suicide the day before all churches merge into the King James Church of Christ.
(a) Live on as before;
(b) Live on as before, but go kosher;
(c) Live on as before, don't go kosher at first, but read the KJV Bible really, really carefully to try to figure out whether kosher still applies or not.
(2B Twist) After God's appearance outside the U.N., the world has changed a lot (becoming kind of like someone's take on The Handmaid's Tale who hasn't actually read the whole book). God has revisited the planet a few times to show people how He makes inter-dimensional portals that transport the souls of the dead either to Heaven, or to Hell. Thousands of reliable, respected people have come back from Heaven to talk about how blissful it is, and how they now understand exactly why Muslims and gays are evil. Thousands of other formerly-reliable, formerly-respected people, including Richard Dawkins, have been given brief parole from Hell to talk about how incredibly terrible it is, and how they now understand exactly why what they did was wrong. God laughs mightily at them before parading them back to Hell.
God brings Satan to the U.N. a couple times for a show-and-tell, allowing Satan to demonstrate the power of his trillion-demon army of sadistic, un-killable executioners. God also appears in the form of Jesus to give an address on how He doesn't require the celebration of Christmas, but how it can be a pleasant reminder of kinship. Then He says that He will be leaving for another few thousand years, and hopes that we don't forget His rules by the next time He comes back.
The world's governments develop patrol squads to respond to allegations of underground homosexual behavior, and criminalize the act of failing to eliminate known homosexuals from society. Giant holograms of Leviticus 20 and Romans 1 play ceaselessly in cities across the world.
One day, you are going to visit a friend's apartment to return his handgun from the repair shop, when you pass by an open doorway. You glance down to see that the lock has broken, and glimpse, through the crack to the open bedroom door, two men in flagrante delicto, having anal intercourse. They hear the creak of the door from the air vent, see you standing out there with the gun, and gasp in terror.
"Wait!" begs one.
"We're in love!" says the other.
(a) Go in and shoot them yourself;
(b) Avert your eyes, walk away, and call the Sin Response Squad's emergency number;
(c) Avert your eyes, walk away, and never mention it to anybody for the rest of your mortal life on Earth.
(2C Twist) Same scenario as 2B, but if you chose to walk away, the neighbor across the hall opens his door, sees you walking past, sees the crime in the other room, and grabs his phone to call the S.R.S.
(a) Shout, "Thank God you have a phone! I was just running to my friend's place to call that one in!"
(b) Hurry back into the gay men's apartment to shoot them, thereby exonerating yourself before God as well as society;
(c) Fake chest pains and/or lamely pretend that you "didn't notice what was going on in there" when the S.R.S. shows up to question the building's inhabitants;
(d) Something else?
It's easy to say you'd choose "shoot," but do you really have it in you? It's also easy to say you'd choose (d), wrestle away the neighbor's phone, help the two guys escape, and start a revolution that ends with a bunch of your fellow revolutionaries betraying the rest of you to your death, but when you contemplate the reality of a million years of being skinned alive, followed by another million, followed by another, do you really have it in you?
