sorry, didn't realize this was the main point

I've never read the Olympics code, list of principles etc, but I can imagine there's something about human dignity and freedom and liberty? Well, liberty should be a lowest common denominator. I.e. -- your culture allows some people to enslave and oppress other people, and deny them life, property and dignity? Well your culture is a piece of shit and you don't host Olympics. Easy! Cultural bias? Sure - cultural bias of human against blood-sucking goblins doesn't sound too bad.
