You just don't quite know when to shut up do you?Nah no black/slave jokes, I can only joke about Irish as half my family are. I gotta few good potato ones if your interested
It's very rare I get involved with threads like this, but the whole "half my family are irish so I can make jokes about in extremely poor taste" argument holds as much weight as the "I can make black jokes cus my friend has a black friend" argument.
People have already stated they don't like you, learn from this, try and see where they are coming from, apologise and try to be less offensive so we can all get along.
