It's discrimination, racial discrimination, to exclude a race, is it not? If you open a place that allows white people in, but tell blacks they can't come in, then that is discrimination, is it not? So if a group of blacks say that whites aren't allowed, like say some college "safe spaces" then how is that NOT discrimination based on race, and therefore racial discrimination?
Again, just like the left, you're blinded by skin color. I am quite sure no living black person here in the US has been a slave. That is just an excuse to keep blacks voting democrat.
