What Is It With Brad Pitt?

What is it with this guy? I like him as an actor and all, but geesh. Last year, he felt important enough to tell a Senator what he could do. Now, he's campaigning for gay marriage by threatening to not marry Angelina until "everyone else in the country who wants to be married is legally able." Does he really think the voters and legislatures of this country are so concerned with his marital status that they will legalize gay marriage just so he can marry Ms. Jolie? Just how important does he think he is?
