I mean, gender dysphoria is real, although we don't know what causes it and if it's a culture bound syndrome or something more generalized. People with it deserve treatment, whatever that might entail. However the evidence that all this hormonal and surgical shit helps people with GD is terrible. It's bizarre political pseudoscience.
I also would note that people with intersex disorders do not have higher rates of gender dysphoria. Growing up with (say) ambiguous genitalia is one of the few cases I'd sympathize with as far as trooning out, but alas, it seems like people with some goofy genital issue still know they're male or female, just with some annoying disorder. Trannyism is just a rich person's mental problem, like anorexia or cutting.
