I fail to see how trans-gender individuals receiving gender-affirming treatment is "pseudo-science", the science is rigorous behind gender identity. It's not that there are more trans people, its that if trans people come out they aren't hung. We saw a similar thing with the statistics for gay and bisexual people a couple of years ago, its merely the fact that people are accepting that trans people exist now.
The "science" behind "gender-identity" is very, very weak. In the United States, most of it is an offshoot of research that was done at Johns Hopkins back in the 1960s-70s, which none regard with any credibility now. Douglass Murray's "Madness of Crowds" does a very good job explaining the history, relevant to that specific issue.
But the bigger issue is with psychiatry, as a practice. Psychiatry functions by defining "abnormality" or "deviance" against some non-specific norm that, more often than not, turns out to be normative, subjective moralization dressed in the language of ostensible scientific inquiry. Foucault was really the first, at least before the behavioral revolution (a move in social science and psychology in the 1960s-70s to focus on that which was empirically true according to sound scientific inquiry, and against all else). He is largely responsible for why, for example, the DSM-IV did not regard homosexuality as a psychological disorder but prior versions did.
Foucault's points are more complicated than I care to type for the moment, though maybe we can talk about it on Discord at some point in the future. But for our purposes now, the issue is that science cannot tell us what constitutes a subjective interpretation of behavior that conforms or does not conform with what is, in the final analysis, little more than gendered stereotypes. Yet, this is the beginning and end of what the "science" on "gender identity" is. The very concept itself does not even lend itself to empirically measurable criteria.
So this places us in the epistemological domain where were trying to figure out what is true based on individual's subjective reports of what they say their "gender identity" is. And so fine. But, as you noted (correctly) the sociocultural turn towards embracing something does invariably lead to a whole bunch of people wanting to jump on the bandwagon. In social science and/or psychology/psychiatry, we call this a "cascading" effect or "snowballing," in lay terms. And just as many of the kids/teens/young adults who "came out" around the early 2000s-2010s, turned out NOT to be gay in the end; we should have every reason to expect that at least a non-trivial percentage of "trans" people in that same category in the 2020s are going to realize at some point in time that, in fact, they are not "trans."
There are already early signs of this, although the magnitude of the problem is largely under-reported. No shortage of horror stories give life to the horrifying data behind namely those young to adolescent boys and girls who underwent one or more of the so called "hormone therapies" or "reassignment surgeries," for the purpose of curing their self-diagnosed "gender dysphoria." I forget his name. But there was a Ph.D. in psychology from Northwestern that did his dissertation on this in 2017 or 2018.
The major concern here is that if you come out as gay, but later change your mind, the risk is fairly low. At least biologically. But if you undergo puberty blocking pharmacological "treatments" or hormone replacements (which are, if you were curious, the same drugs used to chemically castrate pedophiles and gay men for many years, like Depo Provera), the impact on a non-fully developed body's biological process is irreversible. That means if the girl who flirts with the idea of being a boy decides to take testosterone, she will be infertile. As will the boy who decides to take estrogen or other similar HRT-like products. Moreover, there is absolutely no evidence of any clinical benefit to any of that. The post-use rates of suicidal behavior and ideation are horrifying; you're far more likely to contemplate and act upon the urge to kill yourself after taking HRT-type drugs, than before --- in direct contravention of the claims made by ideologically possessed fake experts.
Read Madness of Crowds' chapter on this subject. And then I've got some more reading material for you on psychology, generally. We will then see if that changes your mind.
