CMV: Puberty blocks and gender reassignment surgery should not be given to kids under 18 and further, there should be limits on how much transgender ideology and information reaches them.

Also wrong.

You haven't established that any of the other stuff they said was wrong, so you declaring that also wrong doesn't really hold a lot of weight.

In order:

That someone can get it under 18 years old doesn't mean that they are. So you didn't show that their statement was incorrect
You confirmed they were correct about buying OTC puberty blockers
You pointed out that their statement was unsupported, not incorrect (though anyone who cares to, at all, can easily find reputable support for it)

So I'm less inclined to believe you when you say their last point is "also" wrong. (and is also a statement you've made without supporting it)
