Think about what referring to French people as “cheese eating surrender monkeys” really is. Maybe I’ve had a humour bypass, but it sounds like bigotry to me. I don’t think it’s funny to continually disparage a whole nation on the basis of something that happened over fifty years ago. It’s history. Get over it. Laughing at those stupid French people. Hur hur hur.
It’s not acceptable any more to laugh about how all Germans are Nazis. We’re all enlightened enough to say “Hey, that was a long time ago, The Germans can be groovy people now”. Offer the same courtesy to French people. Outdated and offensive stereotypes aren’t funny any more.
