So what protections are in place in the US to prevent surgery being done for the same ‘wrong’ reasons?
The difference is you're not forced to get it under the threat of death. And I'm not American, but as far as I know you also need a psychological evaluation to get it.
If the healthcare system was actually brainwashing people into getting surgeries they don't need that would be a general issue, not specifically a trans one.
In reality the regret rates for gender affirming surgery is usually found to be under 1%, which is extremely low and lower than almost any other type of surgery. See e.g. A systematic review of patient regret after surgery.
I don’t think people are saying you shouldn’t protest the genocide. You should! But it’s stupid to not vote for Harris over it because letting Trump win doesn’t just throw women, LGBTQ people, etc. under the bus, it also makes the genocide of Palestinians even worse.
