I think this were the case then why do so many threads get locked? I for one don't have the answer to that.
However, I think it is somewhat easy to tell that there is a difference between joking and actual intollerance. Intollerance IMO should not be acceptable on any level. Joking or otherwise.. Words like nigger may really funny on a chat board to some and considered"harmless" -but it is still wrong. Where is the line drawn.
It is pointless and immature..but try to remember that George is triing to sell products here as well. And if there are racist and other bigotry remarks. etc..I don't think people are going to be shopping here for long.
