Nah, you need to educate yourself instead of regurgitating talking points. Not only is regurgitating messy, it's puts a strain on your esophagus.
Historically, Islam has a long track record of conquest---going back to its inception. Groups like ISIS make appeals to that history in sermons and their recruitment rhetoric. All you need to do is listen to them and they will tell you why they do what they do.
ISIS's objective is to spread their version of Islam. Period. Now, are they pissed because the infidel crusaders invaded Iraq and soiled their land or whatever? Of course they are. But even had we not invaded Iraq, their religious doctrine *compells them* to attack the filthy infidel.
ISIS threatens Europe because they can get there relatively easily. Period. We should be thankful they have to cross an ocean to get here. ISIS has killed countless Middle East Christians that had nothing to do with invading Iraq because they aren't Muslims and their religious doctrine *compelled them* to. Period.
Educate yourself about radical Islam instead of spouting idiotic talking points.
