I really like the first half of your post because it actually raises some important questions. What draws people to these groups especially from countries where they should be having a good quality of life. Maybe if there was a serious discussion on why these groups keep popping up in the middle east we might be able to start trying to solve the problems instead of bombing the symptoms.
The second half of your post is just ridiculous. Christians, Jews and Muslims have all done terrible things in the name of religion.
