… only recognising 2 genders while wanting everyone to be free to be themselves …
This is an American tradition. In our jurisprudence, we have a famous saying about how the right to swing your fist stops at the tip of my nose. In my time, that argument was adapted for everything: Your right to free speech stops at someone else's ear, for instance.
It was a bipartisan thing, but only ever worked one way, and was never an equal protection or equal justice thing.
And if, in Reagan's America, someone had said,
"This is how you end up with fascism"↗, those would have been fighting words.
The idea that your right to exist ends when it displeases a conservative is part of the American heritage. It's been this way all my life. Indeed, we can follow it back to before the Republic; it has always been part of our American experience.
Like I said,
the other day↗:
It's one thing to observe the political and historical condition of the anti-trans argument, including its easy and even comfortable coincidence with traditionalist prejudice about the proper role of a woman, but the real problem, here, is that they don't have the science on their side.
So, like creationists, homophobes, and anti-abortionists before them, the anti-trans movement requires redefinition of terms, including medicine, before their arguments have merit. That's why on social media they're just screeching over and over and over again, in hopes of conditioning the audience.
How far back should we reach, in order to make the point? It's not impossible, in these United States, to find people who both believe in the one-drop rule
and worry about miscegenation through transfusion. Compared to what constitutes conception, or an abortifacient, or which born women are men, no, most people would not validate the blood-transfusion fears according to the science. However, when we talk about discontent, and people who feel abandoned or persecuted by society, these folks get counted in with the kitty litter family values totally notaracist anti-woke smarter-than-thou antivax protectionists who require extraordinary justification
a priori because their arguments don't work without special accommodation, but we won't refuse outright because we wouldn't want to be seen silencing opposing political views.
The value of
tradition in the U.S. is nearly incalculable, and the trick is in how an argument hitches on. In that way, we can really pare down the list: Who appeals to the traditional family? (Heterosupremacism (anti-gay/anti-trans), misogyny, anti-science, anti-miscegenation, Christianist.) Who appeals to traditional pride? (Heterosupremacism/misogyny [fundamentally linked], white supremacism, Christian supremacism.) Thirty years ago, it was an edgy comedy bit about Angry White Male Syndrome, both safer and more rhythmically accessible to leave out "Christian", but that's the thing, it was obvious and implicit. Moreover, it's actually really hard to have this discussion seriously as a society; traditionalism objects.
There is, actually, something of a psychological explanation, a strange manner of envy only achievable in extraordinary circumstances. It's a petulant response to
thirty↗, even fifty, years of losing on the merits.
