What is 'reverse' sexism or racism? Isn't that just sexism and racism? Whether you're oppressed or not has nothing to do with how the culture generally treats you. If you're being oppressed you're being oppressed in a single scenario/instance. There do exist general trends on who is oppressed and who is oppressing, and those are worth talking about and being aware of, but I wouldn't ever go as far to say that the existence of trends justifies marking any complaint that doesn't follow those trends as invalid.
