But the GOP leaders are being racist, Trump is pushing the "every Muslim needs to register and be in a database" angle, You know who else did that? The ****ING NAZIS. Most times comparing anything to Hitler/nazi germany is out of line, but in this case, it's extremely relevant. Rubio is basically saying that anywhere Muslims congregate should be shut down (Mosques etc) I'm not making any of this up, these are all things said by them, and endorsed by a large number of their followers. They (Trump, Rubio, Christie) all of those governors are being racist, ugly, bigots. That is the reality, I'm sorry if that by calling them what they are is "hurtful" I find their acts, and their followers to be much more hurtful. We should be ashamed (I already am) that not only are some of our "leaders" spouting this bile, but that a good chunk of their followers are agreeing. Disgusting. As far as how/why are we responsible? Uh, did you forget the disaster that was the Iraq war? Do you really think that had nothing to do with the destabilization of the entire region and thus the rise of ISIS? Lastly I will repeat again: Since 9/11, 750,000 refugees have come to the USA, 0 of them have carried out a terrorist act. Hell, every single person involved in the Paris attacks had a EU Passport!
