Of course, it has been used to just the opposite ends, too.
Little wonder that slavery first died in the Christian world (it's still going on in forms in the ME, in Africa, and Asia). Ever heard of John Woolman, arguably the first abolitionist? Go read some of his diaries, and he'll raise the hair on your neck, but he was a hardcore abolitiionist.
Let's get this straight: the Civil Rights movement was led primarily by:
A) Hippies
B) Gays
C) Church leaders
D) the girl scouts.
Correct answer? I'll let you fill in the blank.
The genocide of Jews? Ever read how the Vatican was involved in just the opposite during WWII? Or are you actually relying on men like John Cornwell and their accounts on history? There is a reason listening to Vatican Radio was a crime punishable by death in Nazi Germany. Sure, you can go back several hundred years ago to the pogroms.
This is a giant stretch, to say the least.
