I'm not sure you understood me/not sure I communicated my point well. I never said anything about who can identify with what type of character. I think it's perfectly natural to have more trouble identifying with characters who are physically unlike you. That makes psychological sense. This is obviously a somewhat salient discussion, but all I said above was that I think it's okay for developers to decide that they want their game to be racially diverse. And that it's okay if they choose to respond to feedback that says it isn't diverse enough.

Your response to my quote seems to break off into a tangent that doesn't really address what I meant. Not all demands for character-level racial identity changes are created equal because "make games more diverse" is not equivalent to "make games less diverse," which is the key difference between people demanding more racial diversity in games and someone hypothetically demanding all-white humans (or, in this case, making a mod that does that). The problem of collective responsibility and how consumers should distribute blame is an interesting one, but not really what I was driving at.

To address your last point, I think that it's far to point out that Stellaris deals with xenophobia, but it deals with interspecies conflict, not ideologies of intraspecies racial purification. I can certainly understand the roleplay argument—maybe you want to pretend that that the humans in the game are White Nationalists who have successfully come into power and "purified" the human race. That's a somewhat interesting scenario. But, at the same time, I can see why a developer might be wary of mods that could empower racist fantasies. I don't think it's crazy for Paradox to curate the things that people are appending to their game.
