That's a good question DS. I'm Polish-Irish and I just can't comprehend getting offended by things like this. I like "dumb polock" jokes, I think they're funny. I like gangster movies with Irish people in them. There's nothing wrong with it. It's not a judgement of the entire culure (well, I guess the jokes are but they're harmless), it's just the portrayal of on Irishman, or Italian, or Cuban, etc. doing bad things. It's an entertaining movie, end of story for me.
