I completely disagree with you. Since you think that Islam is a barbaric and violent religion, I'm assuming you watched, or read articles/videos using multiple verses from the Quran about violence and beheading people and etc. I recommend that you take a little of your time to read the following page; en.wikipedia(dot)org/wiki/Quran_and_violence
Those verses were based off of war, and that page will explain everything. If you take a look at previous comments, some people are no different. For example this mongoloid "They are disgusting animals that should be tortured and shot.". Every single muslim I met in my life has been against ISIS. ISIS uses islam as an excuse to murder mass, they are on another level of extremism. Just like the Nazis.
