IIRC, 70% or more of transgenders are on the spectrum for Asbergers, have OCD, ADHD, clinical anxiety, etc. Note that the trans-cult will push it that them being “in the wrong body” comes first and “causes” the mental issues.
Of course it is the other way around. And instead of the doctors treating their gender dysphoria as a symptom of their mental issues, they just give them a shot of hormones instead to “make them happy”.
The underlying problems have always been with us. That is the capacity for unusual and inappropriate compulsions.
The content, let us say, of these compulsions, is a matter of the prevailing climate of ideas.
I suspect that in the old days many of these awkward young men and women would have joined the Church. Religion would have supplied the compulsive content.
