The whole point of my reply to your pedophilia analogy was to show it was a false one. But since you want to pursue it, I will simply restate what I said. People don't exterminate pedophiles, despite how much hate they have for them.
So was the acceptance of homosexuals, and different religious beliefs. Remember when women were burned for having a black cat? or when millions died because they prayed to a different god? Believe it or not, I am a cynic, but history has proven that humans CAN learn and be more accepting, granted it is painstakingly slow.
