SEE HERE Who's kidding who? There is this bizarre notion that Islam is peaceful and they're only violent because we make them so. I'm not sure what people who think that way are smoking but they are nuts and likely part of the problem. The fact of the matter is that Islamic operatives have been infiltrating our organizations, government, educational institutions and building U.S. terrorist training camps and other sites for decades. They are laying low for the most part but they're there and they will come out in the open when they are ready to attack. The only moderate Muslim is either one who is faking it or someone who's not really a good Muslim. All committed Muslims are like ISIS but may not be out in the open.
There are two main factions in Islam which is a weakness, the Sunni and the Shia. The Sunni make up almost 90% of Islam (87%-89%) and the Shia make up most of the rest. The original division was on the basis of the succession of authority but over the years there has been further division on what is believed and on what authority. They tend to kill each other given half a chance. We should quarantine them and let them sort it out without external help.
