They still don't know what " trans" means though 💀
Still don't understand the very basic concept of gender. I'll quote one of my favorite philosophers, Chomsky:
" The world is a puzzling place. If you're not willing to be puzzled, you just become a replica of someone else's mind."

Nobody expects then to understand being transgender, but not willing to be puzzled and curious about it and blocking yourself from asking questions -- such as how could these people exist in the first place if our views of sexes and gender were accurate.
There is so much easily observable evidence that there is not sex homogeneity between sexes. E.g. tomboys. The conservatives literally divide men into stupid classes based on masculinity -- they literally created a whole Greek alphabet system to describe different genders within man.

They're not right at all. I GET where you're coming from, but I mean -- who is indoctrinating people, the ones forcing sex homogeneity regardless of what people want or the ones saying " you can wear what you want and define yourself however you want, and your sex is not deterministic of your personality or self image"
If anything, we are unindoctrinating child from an unnatural ideology that sees women as physical, emotional and mental subservience to men. I'm glad to read you are smart so you already picked up on that being the reason that it exists.
I mean indoctrination is a stupid thing to say anyway, because there are tons of religions and cults in the United States that indoctrinate children.
Which is more unrealistic of a belief to indoctrinate your kids into?
A. Joseph Smith found some tablets in the 1800s that no one else saw and then read them to his friend and that's the new word of God, except also the church gets new word from God every 2 years or so.
B. Given that we already know there are some males who more easily identify as females, we should just let them do that if they want to.

This is a precursor to fascism. This same indoctrination logic has also been used against black people -- in almost every decade up until the 70s, not joking.

They made this up for the same reason they made up the great replacement theory. The damage that this narrative has done is also pretty unspeakable, as now families of transgender children are literally seeking refuge in liberal states that won't extradite them and take them in for Child abuse.
