"I don't know whether Barack Obama was born in the United States of America. I don't know that. But I do know this, that in his heart, he's not an American. He's just not an American."—Rep. Mike Coffman (R-Colorado), at a recent fundraiser. Coffman has since apologized(ish).
I always love the suggestion by conservatives that there is only one way to "be an American." By their singular definition, I am not an American in my heart, either.
And I frankly don't think that's anything to be ashamed of.
