Er, leftist Muslim convert or militant atheist (may not be white) or something like that. It never fails that when the left goes on the attack like this it turns out to be one of them that did it.
I guess they haven’t released the identity of the killer but why would they automatically blame Michelle Bachmann or Rush Limbaugh when the Muslims and Sikhs have been killing each other for centuries. There are large numbers of Muslims in this country, it is not surprising if some of them should continue their holy war here in the United States.
