Transphobia to not want prepubescent children to have issues later in life because they were on hormones/surgery they shouldn't have been when they shouldn't have been?
I don't understand what's wrong with someone feeling like they're a different sex than what they were born as, and then changing their current sex to what they feel like their actual sex is.
When I was a kid, sometimes I pretended to be different species than what I actually was/am. Should I have received "species-affirming" care every time I felt like a leopard, a dinosaur, or a hyena?
Gender-affirmation surgery is far more similar to plastic surgery than species altering surgery. (But if someone wished to change their species, I would be against it. It's their body. They should get to do what they want with it)
