Right! It's the religion.
We should all be glad, including Muslims. If Muslims read the Koran and Hadiths for themselves, and stopped letting the Islamic clerics interpret it for them, they would become as violent as ISIS when trying to obey what they read. Think about it. A billion and a half violent Muslims. We'd have to nuke the Middle East just to stay alive in western lands.

The "let's bs their religion" was already attempted, by creating Ahmaddiya. But guess what... every time they open a mosque the other "moderate" Muslims show up to tear it down.
They won't become ISIS - psychopaths become ISIS -, they will start to refute it and force it to be more peaceful as Catholics did by knowing what their religion was doing. Muslims aren't the problem, most of them just want to be good people, as anyone else, it's the religion that twists the meaning of "good people".
