One thing Muslims don’t have is the flower child-make-love-not-war kinda girly men you see in the west. Their kids are ready to wear suicide vests at an early age. Whites have nothing on Islamic fury.
Now, Iranians are tougher, but I've been told they don't swim well and their speedboats have glass bottoms so they can see their Navy.
No, to do that they have to select vulnerable people ready to crack from other issues, such as having committed unforgiveable taboos. The average guy won't fall for that crap. So they seek out the shamed and humiliated who are already leaning towards suicide, and administer drugs and psychological pressure to push them further. Note that many suicide bombers are women. Since it is easy for the islamist to destroy a woman's reputation in their abusive society, it is easier to get women to do the work the leadership should do for itself by simply discovering any dirt she may want to hide or failing that by destroying her directly with accusation and rape. If Islamists truly believed their own tripe they would consider such people unfit to do holy deeds and reserve the privilege for themselves, but as we see, more often than not the perp is an emotionally broken person looking for escape, or or retarded soul who is unaware of what he is doing, not a gloriously brave hero confident in his ideology.
As my nephew noted when he was in Iraq, Zarqawi's people couldn't even find enough suitable subjects among the "sinful" and broken then so the Islamists frequently chose to use people with mental retardation who didn't know any better, and drugs to addle the minds of those who were reluctant.
Islamists are not supermen- they are quite the opposite. Islam is not a superior ideology, it is inherently weak which is why fear of humiliation has such power over their thought processes.
