Yes, yes he actually said that – today.
Beyond the insufferable willful blindness to avoid calling Radical Islam “violent extremism”, and against the backdrop of ISIS today holding two Japanese hostages under specific threat of beheading, our Secretary of State:

“Today we are witnessing a criminal form of anarchy, a nihilism which illegitimately claims an ideological and religious foundation. Against this enemy we are increasingly organizing and fighting back. But in doing so we have to also keep our heads.

Obviously the biggest error we could make would be to blame Muslims collectively for crimes not committed by Muslims alone. Crimes that the overwhelming majority of Muslims oppose. Crimes that their faith utterly rejects, and that Muslim leaders themselves have the greatest ability to address. Religions don’t require adherence to raise villages and blow up people.”
