Exactly. Picking on any specific category makes me sad about human kind. For example I like to joke about Italians and their food obsession, but I'm not laughing AT them, I am not viewing myself as superior. Most times cultural differences are awesome to observe, none is better than the other. It's so easy, in case things go bad and, say, a war starts, to fight against other categories. Think cartoons making fun of jews in the 1930's -> the holocaust.
