>Where did this guy get the hate that filled him?<
With all due respect, this is the first time I've heard a Muslim apologize for what one of his own did. That said, this guy, and all "the guys" who are hate filled, got it on his father's knee, in bedtime stories, in morning prayers, in school. He practically got it from his mother's milk. And it came from the Koran. There is but one God, and He is not hate filled. Satan fashions himself as a God, thus Allah is praised by his fervent followers. To keep in control, Satan divides with hate. IMHO.
I thought I read somewhere that this guy was a convert. Perhaps that's not accurate.
