Kids' feelings bounce around from day to day and month to month, and a large percentage of kids with gender dysphoria have comorbidities like depression or being on the spectrum. It's also the case that a lot of these kids end up being gay. Do these kids really have stable feelings, and can they really understand their own sexuality and romance and so on? I think we've evolved to go through puberty, be confused, and come out the other end with a more stable idea of who we really are.
Yeah and from that doesn't follow that it is so in all cases for what gender you end up with versus sex.
Now the problem I have with the demand for logic and science, is that good and bad is a first person subjective experince and it is not always the same for all humans. So if we make a rule for good and bad, that overlooks that it has some variance, we, the bad people, can end up harming people and we don't know it, because we are rational, use logic and evidence and thus is not real, that these people feel harm.
So yes, a part of reality is objective, but it is not objective that there are bad people or if someone feels good or bad.
