Given we've had black, Asian, Israeli and lesbian astronauts, your politically correct racism is a bit out of tune.
If you prefer to believe that there's such a thing as "reverse racism" that's in anyway comparable to - or even worth mentioning in the context of - what's very blatantly happening in regard to the situation Puerto Rico right now, that's one thing. But if you're going to play the "headcount" card - it's not like the current administration gets any saving points for the demographics of astronauts put in space by previous administrations.
And to bring up Sally Ride, who was not only closeted at the time of her mission, but for decades afterward (up until her death in fact) as some kind of an example how "already diverse" the space program has become - let's just say that doesn't exactly buttress your point.
