Sure they Hijacked the religion.

But when is the last time a KKK member set off a bomb at an airport,  shot up a nightclub, drove a truck into a crowd, threw someone off of a roof to his death for being gay, used car bombs to kill innocent people, kidnapped citizens for torture,  detonated multiple suicide bombs, countless car bombings, stabbing attacks, in the name of ALLAH? 

I will educate you on YOUR religion that is the ONLY major religion not to have gone through a reformation.
