"On these sites and in e-mail barrages, he is portrayed as the son and stepson of Muslims from Africa and Asia, who worshipped in mosques and madrasas as a young boy. That is a proven falsehood surrounding a tiny grain of fact"

Is the liar saying that his dad wasn't a muslim? Is the liar saying he didn't attend a Madrasa? These are all FACTS not opinion. A madrasa is a muslim school. That's the definition. It can be radical or not. And Obama went to one.
