Al Sharpton is many things. Knowledgeable is not one of them. In fact, he has no idea what anyone is talking about. He's completely out of the loop, doesn't understand what's going on, and lives his life in a constant state of befuddlement.
These are not merely spurious accusations. I wouldn't make a claim like this willy-nilly. Sharpton himself has acknowledged his confusion on multiple occasions. To prove it, the fine folks at The Washington Free Beacon put together an epic montage of Al's ongoing lack of understanding.
He just doesn't know what people are talking about!
