This situation is volatile, a situation that I don't have enough comprehensive data to form an argument. Merely, I know Breivik called himself a Christian, but then again I could kill people and call myself a Christian. Doesn't make me one. The thing is, radical Muslims follow the fullness of the Koran---they KEEL the infidels.
There isn't a majority OR a minority that stones homosexuals or stones disrespectful children, etc. Do you know what Sharia Law is? I had the "pleasure" of watching a man have his hands cut off for stealing---saw it on YouTube. Crap like that happens under Sharia Law in those nations. Christians don't do that.
There's a difference between nutjobs who think they're Christian, and a large following of zealous Muslims who follow the Koran "in full."
