Only Muslims can end their violence at the source, but we can end it on the receiving end. We can't stop them from abusing women in their own country or minorities or animals, but we can stop them from abusing us
Who is responsible for Muslim violence? Anyone but Muslims. When Howard W. Gutman, Obama's ambassador to Belgium, told his audience that Jews should be accepting responsibility for the violence practiced on them by Muslims, because it's their own damn fault for insisting on having a Jewish state, the State Department wasn't willing to stand behind his words, but neither did it disavow him.
Imagine for a moment if Howard W. Gutman had adjusted his red hipster glasses and told his audience that Muslims should take responsibility for Islamic terrorism. Hillary would have personally fired him, after yelling at him for a good thirty minutes, and Obama would have issued an apology to the Muslim world. Every newspaper column on both sides of the Atlantic would have spent the better part of the week denouncing Islamophobia and clucking over how mainstream intolerance has become.
