Yes, for me this is one of the most disturbing things.
In previous generations, children grew up believing that a boy is a child with a willy and a girl is a child without a willy. Very occasionally, someone - usually male - would reach adulthood with long term, persistent dysphoria, and after researching the subject, would learn about transgenderism and the fact that some people take hormones and have surgery to ease their dysphoria.
Now children are being taught that they can choose whether to be a boy or a girl. God only knows what they believe boys and girls are, but they believe they can choose. In the same way that kids believe in Father Christmas, the Easter Bunny and the Tooth Fairy. So a little boy decides he's actually a little girl, and, encouraged by well meaning teachers and parents, changes his name and pronouns and starts wearing dresses. Children eventually realise that Father Christmas, the Easter Bunny and the Tooth Fairy aren't real. But boys and girls are real. So those children are never going to get to an age when they and all their friends realise this stuff isn't real. But they are going to get to an age where, despite having genuinely believed for the last five, six, seven years that they are the opposte sex, they learn that they are going to go through the "wrong" puberty.
What the hell do you do at this point? You either say, "Actually, we lied to you, you were a boy all along, and now you are going to go through male puberty and become a man, sorry about that!" or you say yes to puberty blockers, cross sex hormones, surgery and all the rest of it, meaning that that child has no hope of ever living a normal life, will never have children of their own or any kind of sexual function.
Is this really supposed to be the kind option? Kinder than saying, "No dear, you've got a willy, that means you're a boy"?
