I'm not sure I can believe that the Quran is any more violent than the Bible. And as I recall, the Bible also demands that everyone in the world become Christian. I think it really comes down to what the religious adherent wants to do. If they want to kill, they will kill in the name of their religion. If they want to spread peace, they will spread peace in the name of their religion. It's part of human nature. Saying something like Islam should be destroyed only raises the question of why Christianity shouldn't be destroyed, or why all religion shouldn't be destroyed.

Also, I love it when people use huge multicolored fonts. It's like a "Do not read this" flag, a real time-saver.
