The Obama administration is quite worried about stereotyping Muslims as violence-prone terrorists. They fear that any acknowledgment that some Muslims commit acts of terror because they are religiously motivated (however twisted the terrorists’ interpretation of Islam may be) is to encourage a backlash of intolerance (at best) and violence (at worst) against Muslim Americans.

It’s not crazy to worry about anti-Muslim violence. There have been vicious attacks on innocent Muslims. Last November, a Queens, N.Y., man was stabbed six times as he stood outside his mosque by an attacker who shouted “F—— Muslim, I’ll kill you.” In the wake of the Boston bombing, a drunk Northern Virginia man reportedly attacked and broke the jaw of a cab driver (an Army reservist who served in Iraq and at Guantanamo) after snarling “If you’re a Muslim, you’re a (expletive) jihadist. You are just as bad as the rest of them.”
