I wonder what the same people criticizing trans health care as "mutilation of children" think of intersex babies having genital surgery forced upon them to align their genitals with gender binary ideals.
And just before anyone has a chance to say it, trans healthcare for teens is okay despite them not being able to consent because if they don't choose quickly then one of the options is going to be forced upon them.
It's like a child standing on train tracks with a train speeding toward them and the child expressing that they'd like to get out of the way while people telling them "No! You're not old enough to make that decision!"
