You should learn to read more carefully, because I did allude to other groups. Why didn't I specifically mention other groups? Because Muslim extremists have been responsible for a disproportionately large ratio of the terrorist attacks in this last decade. Further, regarding terrorism and issues like the Rushdie fatwa and the Dutch cartoon controversy, even moderate Muslim groups have been less than vocal in their opposition to the associated violence and intimidation on the part of fanatics.
If I seem to insinuate that your average Muslim is more prone to terrorism, or any other crime, you misunderstand me. If I appear to suggest that normal religious people are more prone to violence than irreligious people, understand that this is not and never has been my view.
I believe religion enshrines a number of ideas that are conducive to or lead to favorable conditions for extremism. I believe extremism in any form is bad, and that religion is not the only or main or necessary source of it. If the disgusting child murderer was partially influenced by his religious views to take lives, I do not think that can or should be interpreted as a mark against moderate religious people, and I certainly wouldn't consider religion solely accountable either. If that's not good enough for people who are itching to play the anti-religious bigotry card, I don't know what else I can do. I've represented my opinions truthfully and I trust I don't hope for too much when I ask others to do the same.
