Sorry for the delayed response, missed this somehow until now.
1) Ok yeah, I accidentally got the timeline wrong. I was thinking about this image I'd used before, which was so long, with so many "science" doomsday predictions, that I forgot it only covered 60ish years.
2) Transmen are not men, they're transmen.
3) Prepubescent children explore a LOT of things, often dangerous, because their brains aren't fully formed. In fact "the science" says human brains aren't fully formed until about 25.
Children are living mirrors, they reflect what's around them in order to find acceptance while they grow. It's an inherent survival trait, much like neoteny. That's one reason you see more "trans" kids in places like California. Another is parents *pushing* the ideas on their kids for the sake of the parents' own acceptance. In other words, it's less nature and more nurture.
What if there was a child whose father, or best friend, had amputated legs, and that child felt like their own legs were bad and should be amputated, even though they were perfectly healthy. Should that child be allowed to have their legs cut off just so they can feel acceptable to their father or friend?
Letting children explore who they are is one thing, allowing them to begin procedures that are undeniably and irreversibly harmful to them is straight up abuse.
And if one can argue a prepubescent child is mentally developed enough to decide they're the wrong sex, how long will it be until one argues that a prepubescent child is mentally developed enough to decide to HAVE sex? Both are equally harmful to young children, but the first is literally happening, and the second is getting closer every day.
Bear in mind, I do know there are genuine trans people out there, either due to mental issues (caused by sexual molestation, for example) or straight up birth defects that caused the wiring to get crossed, but not nearly as many as are claiming association with the trans community - especially "enbys", who are in no way trans, and are actually harmful to the true trans community.
4) As for the "non-men" thing, that was a directive from Johns Hopkins University, a bastion of wokeness.
