Yeah Oz, some of it is culture too, agreed...but I have read stories of 2nd & 3rd generation transplant muslims growing up in the UK becoming terrorists, which means that the islamic religion itself has some attraction to violent extremism. Also culture and religion are inseparable with islamic fundamentalists. Just like any religion, it depends on the interpretation by the leaders but there is some strong language in sharia law that is more demanding than other religions. I think islamic traditions are by definition more antiquated and backward (like the Roman Catholic Church in times past).
