Where is the proof that he is Muslim?

I remember one racist old white woman who was against Obama because he was a Muslim and an atheist.

His middle name is Hussein. That's it. That's the most tangible "proof" they have, aside from the fact he's not white and that makes them anxious.

Not that having a Muslim president would be a problem in the first place. The people that assume he is and that it's something to freak out about are seriously fucked in the head.
