I won't risk saying this in real life or anywhere where my real identity is known, but I do wonder if the end result will be similar to what's common in many parts of Asia: a third/fourth gender.

Instead of saying trans people are 100% identical to the gender they identify as, they'll be seen as something different. E.g., In Thailand there's the concept of kathoey (westerners refer to them as ladyboys). The Indian subcontinent and culturally related areas have hijra. They're not seen as the same as women, but they're not seen as men either. They're something else, and it's okay.

I've also seen a lot of westerners trying to push their ideas of gender globally and getting enraged when it doesn't fit. Some people get enraged when, for example, Thai kathoey aren't simply referred to as women, but for a lot of those people in Thailand, they don't see themselves as identical to women. So while trying to stop people from misgendering people, they overstep and misgender people who weren't being misgendered.
