One thing to keep in mind is that the Starfinder setting doesn’t need to be an utopian dream of perfect social harmony. Just because it’s a futuristic setting, it doesn’t need to represent the resolution of all of our own gender issues. On the contrary – I’d much prefer a setting where problems linger, and we can explore them through story if we choose (or ignore them in favor of, you know, space adventurez).
I think the important value which the developers have nailed is representation. Instead of having to fill a gender role, lashunta players are free to choose, and are explicitly shown that this is welcome in the game setting. Crystal Frasier’s added description of the change provides a nicely logical context, which elevates the Pathfinder iteration as well. The lashunta realized they needed progress, and are working through it. The binary gender/caste assignment still exists in some cities. It’s not a clean break, and it wouldn’t be. It makes the game more thematically rich than if the lashunta had suddenly solved all gender issues.
Similarly, with the elves criticism, I get that folks are tired of the xenophobia trope, but it says in the text that many reject this attitude (the forlorn), so it’s not an all-or-nothing deal. I’m sure elves exist in many other places besides Castrovel, and their culture(s) will be more diverse than just those in the ancestral homeworld. So I think it may be premature to say that all elves in the setting are expected or perceived to be aloof and snooty.
One last thing I want to commend the developers on. I’m getting a strong Star Trek vibe from the progressive ideas we’ve seen thus far. All of you familiar with Star Trek know that the series has always tried to champion tolerance and acceptance (Kirk and Uhura’s kiss, for one example). Starfinder is showing a deliberate effort to pick up that legacy, and I think it’s fantastic. They didn’t have to include it in their game (it is just a game, after all), but the fact that they did is both brave and It makes me want to support the game and company that much more.
