Pull that old head out.....of  COURSE it's different!!!!  (And I would submit that the Crusades were a direct response to the moslem attacks on Europe, and those seeking visits to the Holyland...and thank GOD for Charles Martel!!!)  So, in oh, I don't know, in the past 50 years or more, how many witch hunts, and inhumanity have been caused by Christians?   
islam is a violent, political, murderous cult masquerading as a religion.  It was founded by an insane, misogynistic, pedophiliac, goat herder.   It has been at war with the civilized world for over 1400 years....it hasn't, and never will evolve, because it's basic tenets are evil, and to change those would be to destroy islam itself.  It's like communism (murdering hundreds of millions), or nazism (murdering tens of millions).  It is evil in and of itself, and THAT is the problem.  It is very different than Christianity, in the message, and today, in the actions.
