Remember all the times that Barry O has scolded us and lectured us and insisted that he's NOT a Muslim?
It only matters, of course, in that he has repeatedly denied that he is a Muslim. As long as he is not a militant* Wahabi-style Muslim, it would not be a problem had he not lied to us about it all along.
* - I recognize that "militant" is a subjective word. By "militant," I mean "at least as militant as Michelle Obama's eyebrows."
