Look it up, science denier.
Recent studies suggest that learning and using a second language
(L2) can affect brain structure, including the structure of white
matter (WM) tracts. This observation comes from research looking
at early and older bilingual individuals who have been using both
their first and second languages on an everyday basis for many
years. This study investigated whether young, highly immersed
late bilinguals would also show structural effects in the WM that
can be attributed to everyday L2 use, irrespective of critical periods
or the length of L2 learning. Our Tract-Based Spatial Statistics
analysis revealed higher fractional anisotropy values for bilinguals
vs. monolinguals in several WM tracts that have been linked to
language processing and in a pattern closely resembling the results
reported for older and early bilinguals. We propose that learning
and actively using an L2 after childhood can have rapid dynamic
effects on WM structure, which in turn may assist in preserving
WM integrity in older age.

Their brain structures approach those of women. That's biological - you have already set chromosomes aside, and in a conflict of brain structure vs gonads (in those particular trans that have one set of normal gonads) I don't see much reason to elevate gonad biology over brain biology.
There is no evidence that shows those brain differences exist from birth, which is the only way to rule out experience-induced neuroplasticity.
So you are arguing for a third sex? With its own bathrooms and showers and stuff? Because they are certainly not men, mentally. They look like women.
Superficial appearance and subjective feelings only.
I've already said, many times, that they have always used the facilities of the sex they can pass as, without anyone giving it a second thought.
Medicine is not in academia. But you are correct in discovering that academia is not left-leaning. That's an important step, in the US - if you don't make that discovery, you will be vulnerable to manipulators and marketers of swill your whole life.
Medicine requires years in academia, and academia is obvious left-leaning, e.g. all the protests against anything anything but leftist speakers, safe-spaces, language guidelines, etc.. Does none of that reach you in your little bubble?

And?
There are lesbian trans women and gay trans men.
What about XX women who are attracted to women being in locker rooms? What if some of these women were surgically given penises? What if others were under the influence of narcotics and carrying firearms? What if cis women take video of other women in these settings and post it online? What if…?
Genetic men always have a physical advantage over genetic women, as illustrated recently in Texas girl's wrestling.
Not sure what the non-sequitur about guns and drugs is about, but there's already laws against that. Cis women have taken video of other women in locker rooms, and faced criminal charges for doing so.
Are you really advocating trans rights, or just wholly unisex facilities?
Science indicates that the brains of transgenders more resemble those of their desired sex, which would account for their identity issues. So behaviorally they’re going to be inclined to act characteristically in accordance with the desired gender. And in keeping with your neuroplasticity theme, there could very well be additional environmental conditioners to explain the variance in sexual preference. Biological science tends to support the notion that the transgender brain is in search of a compatible gender, and if society has the means to facilitate a solution for that search, then in the name of compassion we should try.
Neuroplasticity accounts for changes to the brain caused by behavior, experience, or environment. And those similarities to desired gender have not been shown to exist from birth, as they would if they were wholly genetic.
It's not surprising that behaving as another gender for years would approximate that gender's brain structures, due to neuroplasticity.
