Yeah, in my layman opinion, no one should even really be concerned with the gender and sexual identify until they’ve gone through puberty. Especially to the point of medical intervention.
That said, if a boy wants to wear a skirt or play with dolls (I mean, lots of action figures are basically just super homoerotic dolls), that doesn’t necessarily mean they want to chop off their dick and become a woman. Just like a girl who likes to play sports and work on cars doesn’t inherently want to be a man.
Now, what a grown adult wants to do with their body is no business of mine, so if you want to go though hormone therapy and gender surgery as an adult, go ahead, I really don’t care what you do downstairs to your body. There’s a lot more real problems in the world than that.
On the note you said, no kid should feel pressured to behave in a way regarding sexuality, which kids often get into way too young anyway, that isn’t natural to them. A straight person pretending to be gay isn’t healthy, just as a gay person pretending to be straight is similarly unhealthy. And some people are, of course, naturally gay. And that’s fine. Do you agree on that point?
You’d think we as a society could just stop caring what type of consenting adults other consenting adults find attractive. If a man likes a man, or a man likes a woman, why is it any of my business? Parents shouldn’t actively be pushing any sexuality on their children. But if a person is actually gay, that’s who they are. It doesn’t make them any better or worse than someone who is straight.
I don’t agree with the idea of raising a kid to be gender neutral though. Raise them like whatever gender they were born as, but let them pick hobbies that are interested in, regardless of if they’re typically masculine or feminine. A girl wants to skate? Cool. A guy likes pink and wants to play with dolls? That’s not the end of the world, not by any means. But that doesn’t mean a parent should start saying the kid identifies as the opposite gender. If they, on their own, start saying that they think they’re the other gender, then go get professional help, as that’s way beyond my ability to help with. But short of that conversation actually being brought up by your child to you, I think treating them as the sex they were born as is perfectly fine.
