Did you know that homosexuality was once considered a mental illness? Did you know that studies consistently link homosexuality with childhood trauma? It's actually amusing to read some of those studies and see how they try to PC that link.
Sometime during the mud drug concert years of the 60s or 70s it was reclassified as no longer a mental illness. By their political allies.
Of course we've seen a more recent version of the same play with gender dysphoria. They're being more careful with it because they still want the whole "we need to provide mental health care to these people as we mutilate them for affirmation" angle.
I would be curious to know what mental conditions are included as illnesses in your data. I remember one psychologist advocating for psychiatric clearance as part of a permit process for owning a gun. When asked what would disqualify someone as not mentally healthy he said "the desire to own a gun."
Funny how that works. Enjoy your data. Watching you apologize for rampant drug use, outdoor ****ting, violent crime, and moral decay is always satisfying.
