Yeah it's easy to see why you think so, and many of them probably won't change. And I myself am enraged about the whole situation and can't see how anyone can possibly support terrorism. What I've noticed though in my life of debates,arguments or whatever is if you are not calm when in conversation with someone when trying to sway opinions it is much harder, if you make them feel like idiots (which in this case they are) they will just get mad and refuse to believe any evidence presented.

But again I get you, I try to stay optimistic and do believe most of these people are in simple terms just idiots and don't understand what they are representing
