You are not supposed to challenge "political correctness"; not with logic.
Actually, the whole incident helped to demonstrate, once again, the best thing that Trump has going for him--he is not "politically correct."
This LSM created phony scandal will get no traction because we the people either know obama is Muslim or suspect it. It will backfire on the LSM in the same way it did when Giuliani expressed his doubts that Obama loved this country. Because again the people knew what he said was true.
