i dont beleive islam is any more violent than any other mainstream religion, its main weakness is the culture in the countries who happen to practice it, (whether there culture is because or regardlesss of their religion ill leave to social psychiatrists), ie in turkey, iran and pakistan they are historically more prone to murmoring infighting, not enough to change the balance of power but enough to bring unrest, that kind of always on edge attitude makes them jump down the throats of anyone who critisizes them regarding religion or anything else. "conflict breeds supremacism" so to speak, the arguement i would make is that most of their conflicts have had religion at the heart of them make them double quick to jump to the defence of their religion, even if its a valid criticism.
