It's really very simple.. White people don't want to be anything, but White. I can't relate to being, or envision myself as an inferior race. And I don't ever want to. However, other races love to imagine being White. It works for them and makes sense. That's why race swapping is not really an issue for other races, because it's natural for them to fantasize about being White. However, it doesn't work vice versa for us.
