I agree with your article, but less of it coheres with my experience. A Colorado medical school professor as recently as 2022 told me that I have a "chemical imbalance" inside of my brain during a video consult. She is now tenured. A more recent interaction with a PMHNP also stated I have "too much dopamine" and that I could "literally die if you don't take vraylar". (I'm still waiting to spontaneously "die" months later; any day now, sigh).
I believe what fuels much of the disillusionment is that these categories are taught as if they're A). homogeneous, B). static, C). a-contextual, D). overdeterministic or unidirectional. And it's because all of science holds the same assumptions with everything they theorize. E.g. Physicists demand spacetime is perfectly homogeneous, that all "laws" are deterministic, static, and a-contextual and hence generalizable. And when philosophers point out these are instead "first assumptions" the scientist responds with "Well that sounds too philosophical for me so it's not my problem!". Whereas biologists will unapologetically claim nothing living is ever homogeneous, not even "identical" twins, nor are evolutionary processes "purely" deterministic, nor are mutations unidirectional nor a-contextual. Living bodies are also not static (aging is real, circadian rhythms change, values change, habits too etc). And no metabolic process follows a straight line. So why hasn't institutional psychiatry banned these words (homogeneity, static, a-contextual, overdeterministc/unidirectional) yet? What kinds of brains are rising to the ranks of professor to regurgitate these specific assumptions? I disagree it's the general public causing them. Rather, the first time i ever learned of the word homogeneity was in a psychometrics class about "crisply measuring mental disorders", as it were, "carving nature at it's joints".
