I haven't touched the game, but I think it's just ridiculous nonsense!
I'm white (Irish /English/Hungarian) and my wife is spanish, so my daughter is half white/half spanish. I have black friends, my best friend is half black, and we can all voice our opinions and
jokes equally. It's silly IMO.
The people who think that this is a problem must not have any multicultural friends or family at all and need to broaden their horizons!
