Peace! Islam is a religion of peace! (repeat ad nauseum)
When Obama made his speech about how the US was not and never will be in a war against Islam, and stated that Islam is a religion of peace, it seemed to me that he was somewhat angry - as though annoyed about any criticism of violence in Islam. I've never heard him admit even that a rigid interpretation of Islam was being used as a recruiting tool for terrorists (at least not that I remember) - although he could state this without condemning the religion as a whole.
Regarding Islam and peace, why is what happened to Malcolm X never discussed anymore? He was killed by three Nation of Islam members, and had been targeted by the Nation of Islam because he went out on his own and became a Sunni Muslim. If this isn't proof that killing in the name of Islam is sanctioned at the highest levels of specific Islamic organizations, and that thus there is a problem with officially sanctioned violence within Islam that needs to be recognized and addressed, then what is?
This is not to say that there isn't tons of other proof connecting Islam and violence, like 9/11, but the Malcolm X assassination goes back a long way, and is linked to Chicago (via his dispute with Elijah Muhammad and that Louis Farrakhan had said that Malcolm should have his head cut off), and thus is IMHO an important point of discussion.
