“Identity politics” always seems to mean “I am upset that different people exist.”
This is a nothing option in a video game. Nobody’s rubbing your nose in it. It doesn’t affect you, at all, but it’s a neat little extra for other people. Do you give a shit about other people? Or does the mere possibility of anyone distinct from you, the protagonist of reality, fill you with emotions you can’t handle? There’s no third option, here. It’s a checkbox for how NPCs choose voice lines, in exactly the same way they’ve done for decades. It’s just separate now.
But of course one glance at your profile shows you’re an unapologetic bigot, and what you mean by “gEnDeR iDeOlOgY” is exactly what every other diet Nazi means by it: you hate queer people, and you want it to be their fault.
