Aren't parody and satire supposed to be protected? Their disclaimer and various other pages make it quite clear that while they can be offensive and downright abusive to the subjects of the articles found on the site, don't assume what you read is true. They even say that you should "expect blatant, biased lies, and expect boring truths to get deleted quickly." If they weren't allowed to get away with this, then, in all fairness, wouldn't you also have to send the Gestapo after Uncyclopedia and The Onion as well? While one may take things much further than the others, they're effectively doing the same thing.
Oh lawd, is I taking the interwebs seriously here?
