"This isn't right" is extremely powerful in a land of soulless politicking, murder and bullshit. Few people even bother discussing morality any longer in the great echo chamber:
"Should we pull out of Pakistan?"
"Does the president have the authority to order extrajudicial drone assassinations?"
"Is the War on Drugs proving effective?"
Vary and repeat as long as ye dare. While the American "left," with its Democratic Party, pursues a contemptuous, hyperscientific, inherently-hypocritical industrial exaltation, and the American "right," with its elephant party, pursues a troglodytic fantasy land of Norman Rockwell paintings, the idea of a "church" remains one of the last remaining socially acceptable venues of shared humanity that could bind those still living on either "side." This isn't right needs to be said and asked and accused and repeated. Asking what Jesus would do is more than (or completely separate from) asking what a historical or biblical "Jesus" might or might not actually "do" in any given situation. It is, instead, an appeal to a higher authority, unbound by memetic tendrils, that can allow the golden rule to shatter social blinders and question the things that aren't supposed to be questioned by pragmatic modern voters.
