What if it wasn't racism, really? What if the sign had said "Chinese people from HK, Singapore, Taiwan all welcome." Sometimes it's easy to use the racism tag, when the truth of the matter might be something else. Perhaps a simple distaste for the way a particular culture carries itself abroad. Even people from HK don't like this behaviour from mainland visitors, and they're both Chinese. If you're totally comfortable with someone's skin colour, but not really into obnoxious, loud, selfish behaviour, does that make you racist? No doubt, such a sign would be very poor form, but it's also time for these tourists to lift their game when they go into other countries and also show some respect - regardless of how much money they have.
