Yes, some of the things people, or groups of people, say is just plain bigoted and hateful. I like to think of myself as a rather culturally, racially, religiously, etc... sensitive person. I study Chinese at university and have plenty of international friends here from all over the world. I've learned a lot from them for sure. Like I said, there is a time and place for the "joking" and a time and place for the seriousness.
