Lets compare the violent manifestations of islam against those of other religions.
Although all religions have been used for violence, it seems that it’s the exception, while in islam it’s the rule. You know this just by a single historical overview of how islam spread through conquest, and how islam seems to be in a perpetual “justified” jihad with everyone who it considers to be its enemy.
And although the Christian ideal is to ‘turn the other cheek’ when “first attacked”, in islam it’s to ‘cut off their arms and legs on opposite ends’ of just ‘strike off their heads’.
Islam is special when it comes to religious violence because it’s taught and instructed directly and clearly in its passages. No other religion commands it’s followers to do such vile acts.
