So, when I see that science fiction has not been "forward thinking" about race, I see reality being put into place. We can all hope that the future will be filled with complete equality, but that won't happen, not unless we do become a country with equal representation of "races" or we all cease to see color/race as an issue.
Unfortunately, as the clever little puppets from Avenue Q once said: Everyone's a little bit racist, sometimes. Go ahead, tell me you're not, because you're lying and you know it (it's possible you don't even know you're a little bit racist).
By the way, this is nothing against the SF Flare folks. I do appreciate the information they provided, but I think we get a bit disillusioned by the prospect of SF being something that, in reality, it isn't. SF can only be forward thinking so long as it is realistic. A liberal fest of social changes on top of the technological changes is asking a bit much from a genre that has to not only accurately portray the future, but also has to be realistic and believable about it. We're no longer in the Golden Age where making everything up works 100%. SF writers have to be, well, realistic. Are black presidents in our future? Yes. Are Hispanic and female presidents? Of course. Do I think they will be a consistent regularity that one could play it off in any story, every single time? No. We don't even see that in other nations we consider more "forward thinking" than us, so why would we expect that a fictional future United States would represent something that likely isn't going to happen?
