The original post was centered on Tucker Carlson's statement that "children's hospitals" should not be performing gender affirming surgeries. You seem to agree with him to some extent, saying hospitals "don't" do gender affirming surgeries on children (though it appears some do).

I think it is fair to say, they "shouldn't" perform gender-affirming surgeries on children. Many mental conditions as evidenced in the case of Chloe Cole can lead to confusion with children regarding identity. The body is being subjected to huge amounts of hormones as the body enters puberty. It takes the brain a few years to catch up.

Having run physician groups, I am surprised surgeons would take on the medical malpractice risk of misdiagnosing a child as transgender and doing gender affirming surgery before they were legally able to make that decision for themselves. Which is why as you say, most facilities won't do surgeries on children and Carlson's point that children's hospitals shouldn't is not an attack on transgender people but a fair criticism of gender affirming surgery on children.

Why make it more than that?

As an aside, 2% is a huge number when it comes inappropriate surgeries. Imagine if I did open heart surgery on 2% of people that should not have gotten it as a result of misdiagnosing their condition.
