I see what I see.
You see a man born to a Muslim, raised in a Muslim home, with a Muslim name, raised in a Muslim country, hosting a Ramadan Dinner, and you see a Christian. And I see a Muslim.
Go figure.
I see a man born to a non-practicing Muslim he never knew, who didn't have any real interaction with Islam until his mother married another man, who spent a few years in an Islamic country and then came back here to be raised predominantly by his grandparents, who certainly weren't Muslims. There is nothing determinative in that description, and I would give anyone with that background the benefit of the doubt if they claim to be a Christian. It's called simple fairness. Particularly since I have seen Obama on camera drinking alcohol and eating pork.
George W. Bush hosted Ramadan dinners and Obama also hosted a Sedar. So what?
