Let me try one thing at this point.
Lets go through LGBTQ.
L and G already fought for their societal recognition successfully - before social warriors were actually a thing.
B comes almost for free with that.
T shouldn't bother anyone too much - simply, because they are a smaller minority (0.5% of the US population) of society.
Q is mostly terminology at one point. (If you dont want to talk "sisgender" I'd actually understand that - because its an actually big departure for everyone to pick up as the new default just because...)
But looking at those groups of people. The percentage of population number they actively concern becomes smaller and smaller.
So is there a real reason, why the efforts "opposing" at least the societal acceptance of that group grow bigger?
Not really. Its just people imagining things, that they'd classify as something "too strange", but which they will probably never have many "issues" with in their lives.
Theres really something to be said to give societal recognition to this group as a whole - and call it progress.
The thing with taking over ll the proposed definitions of "mental gender" as a societal default is a different discussion, and nothing I'd see happening too soon. But at least the recognition that those groups exist and it might be ok for them to do - seems like something thats actually ok.
