I really don't think that they are giving up their lives as much for faith as they are because their lives are so boring, and death seems better than to go on living in their empty, meaningless lives.
Could you live a life that had NO TV, NO radio, NO dating, NO jobs, NO place to go, NO cars, NOTHING to do but stand on the street corners in 130 degree heat and scream about everything that everyone else does that angers them. IF I had to live that kind of life, I'd kill myself too. LOL!
Try to hold off on the "LOL" and use your memory for a moment. The 911 bombers were Saudis. Saudis HAVE T.V. (satellite), radio, jobs, places to go, cell phones, computers, the internet, cars out the wazoo and as much to do as anyone in a small town...and the entire country is like a small town.
They DON'T stand out in the 130º heat because all their homes have air conditioners that can get the temperature down to 60º. I know this because I lived there for five years. It's the same with their cars and where they work. 75 years ago what you said is true, but that was 75 years ago. It ain't like that now.
If you are going to screech at all Muslims AND their faith, because of what a relative FEW do, and it's your right to do so, at least get SOME of your facts right.
By the way, there are 1 billion Muslims and only 1/4 of them are Arabs.
