running amok (lit. going crazy and killing people with a kris, a knife, originally a malay expression) is not necessarily a mohammedan specialty alone. but shouting 'allahu akbar', writing fundamentalist global-conquest, jihadi stuff on the net, and preparing himself for suicide bombing is indeed a mohammedan specialty.
every time a mohammedan does something violent, everyone says it has nothing to do with mohammedanism. on the contrary, it has everything to do with mohammedanism.
the problem is mohammedanism, not mohammedans. any apostate mohammedan is a great guy.
