As for detransitioning, I’ve heard that cases of that are exceedingly rare - like less than 1%.
The statistics you’ve seen, and I’ve seen them too, are a trick.
First of all, how are they defining “transgender” and “detransitioning”?
The kid who occasionally feels odd in their body?
The kid who is cross dressing and has their close friends call them their preferred name?
The kid who cut (or grew) their hair and is loudly insisting on names and pronouns but never took hormones?
The kid who took hormones?
The kid who went and got top and/or bottom surgery?
And the other thing they don’t tell you is that sex change surgery work on the brain very similarly to abortion.
Ask a person who just went through either type of surgery.
They’ll generally tell you they’re please with the results.
But over time, they have a much higher rate of psychiatric, addictive and social problems than the general population.
