It is the Muslim community that has the best chance of stopping and checking and pushing back on people who are trying to politicize their own faith. So this attack on Islam is an attack on a great faith. It undermines the people who are trying to rescue this faith from these horrible people. It endangers every human being on earth because it accelerates the radicalization of some and emboldens the worst elements of that faith. So this fight is a fight I think that we have to take on.

A one-sided analysis of anything always leads you into the wrong direction.
