Try telling that to a terrorist. I'm sure he will say: "Of course! I should just change the calibre of my morality!" This meme applies to everyday Americans, but you can't change the mind of a terrorist or a mentally ill person just by telling them not to shoot anyone. I appreciate your point tho.
I would try and educate anyone Christian, Muslim, Jew, Hindu, Punjabi, Mennonite, Catholic, Taoist, Zionist, Scientologist of the dangers of organized religion that wants to control you through propaganda
