I think the difference here Nevis is that races act as more than just an ethnicity. This is not a case of skin color. It is not just a case of cultural or ethnic differences, it is a case of your race is your "Nation." There is a fundamental difference in the soul/biology of these races. So it's less a matter of civil rights in this arena and more a matter of nationalism. Tinged with a touch of Darwinism perhaps? Depends on how heavy the biological changes are and whether the races are actually different "species."

That said, I'm sure there is some sexism, but it is not done in the same manner as racism. There might be some beings that are chauvinistic or the opposite, but it's not in the sense of there being a lack of rights provided to the individuals because of gender. That's the vibe I get anyways.
