This has got to be a troll. No one can be this much of an idiot. But just in case you are. You gave up your rights when you agreed to Blizzards EULA. In case your to lazy too look it up, here it is http://www.worldofwarcraft.com/legal/termsofuse.html. And in case you are too lazy to read the whole thing:

It's a game, if you don't like it move on to another one. We wont miss you ... really we wont. If you're going to pull the First Admendment card, maybe you should actually read it. And then research exactly what that means. People like you screaming that you're an American, make people like me ashamed to admit I'm an American.
