Hey saxitoxin, I already predicted this long before the scientists did.
The problem is that mental health understanding is on the cusp of a major paradigm shift. The old models literally do not work and do not explain things.
Under the old model people have an "illness" with "symptoms". However, reality shows over and over again that all the mental "illnesses" don't really exist and can just be thought of as "symptoms". The evidence for this is that every single mental illness correlates positively with every single other mental illness. That means if you OCD, you are more likely to have Tourette's, and schizophrenia, and so on down the line.
I have done my own (unpublished) research that has found links between all the mental illnesses and homosexuality. I am not surprised that somebody has found the same links in transgendered people. You can read a helpful summary article here:
https://www.nature.com/articles/d41586-020-00922-8I (and others) have been saying for years that mental disorders don't actually exist - they're all in your head. One of the chiefest evidences of this in my own mind is that the manifestation has changed in popular culture over time. In the 19th century, women would faint all the time. This at the time was an accepted manifestation of mental illness. Now fainting is rare, and often a physical ailment, not a mental one. Prior to the 20th century, schizophrenia was rare (although some try to write down mystics as schizophrenics, I would argue there is something different entirely). Now it is common. We all know that transgenderism is more common now than it ever was. I should also note that the trend I see is that it is common in certain groups. For example, the speedrun community has a lot of transgendered people. You could argue that this is due to an external factor that leads people to like speedrunning video games and changing genitals. I would argue that it comes from community acceptance.
So, in short - speaking of mental disorders is a step up from speaking of demonic possession. We don't want to blame or ostracize the victim anymore than we already do. However, there should still be a stigma around damaging manifestations of this single problem - like transgenderism. By saying "It's ok to be transgender" we are planting the seed in people's mind that "hey, if my mind snaps and I get sick of conforming to the world's expectations, I can just become transgender and then they have to accept me". I honestly believe that many transgender people are doing it because it's a fad or just for shock value when they are teenagers or whatever. However, it then becomes part of their identity and they can not let it go. By calling it what it is - demonic possession, we allow for them to be exorcised and/or cured. There is a road back, you are not stuck with your mistakes as a teenager. There is salvation and there is hope and His name is Jesus.
