False Leftists do not understand where "non-white" representation should be encouraged and where it should be discouraged. If they see more "white" than "non-white" firearm owners, they do not (unlike us) tell "non-whites" to buy more firearms. But if they see more "white" than "non-white" astronauts, they (unlike us) tell "non-whites" to become astronauts. Underneath it all, their chief concern is to get "non-whites" behaving in a way that does not cause "whites" to feel threatened. "Non-whites" with firearms will scare "whites", therefore "non-whites" should not have firearms. On the other hand, "non-whites" becoming astronauts will reassure "whites" that "non-whites" are just as capable of perpetuating Western civilization, therefore "non-whites" should become astronauts.
For True Leftists the answer is simple. It should be encouraged where the result is more likely to undermine Western civilization. It should be discouraged where the result is more likely to reinforce Western civilization. This leads us to the opposite conclusions.
"or that it is "fascist" or "ubermensch" in nature."
To clarify, fascists may not associate space exploration with "whiteness", "heterosexuality", etc., but fascists do like the idea of space exploration. Fascists would even argue that fascism is superior to identitarianism because it would recruit space exploration talent from wherever it can be found and thus have a stronger space program than identitarians with their narrower recruiting. This is why we are not fascists.
