What makes you think such a movement will not bring such extremism in place of another? We don't have to look far to see how much worst a country can become without rule and order, the likes of Iraq after Saddam Hussein was gone...
As for studies? It's only people that think they've studied and understands the situation therefore, they see it as a benefit to side with the movement. What they forget is, those are the same kind of people that shout death to America and other western countries.
