I grew up with a woman who became schizophrenic during my childhood, and when it started happening to her, she was really frightened and confused. Becoming a fundy Christian gave her an (illusory) sense of control because of the strict rules. It seems like that’s what happened to this guy, and he went off because he can’t cope with life. The man is obviously mentally ill. This doesn’t mean he shouldn’t be tried and dealt with, but common sense should tell you that if most Christians don’t go around ranting about sinful sex and Jesus coming, then most Muslims don’t behave like this man, either. It seems to me that religious extremists either usually have mental problems, or are sociopaths exploiting people with mental problems.
