Agreed. The idea that skirts are associated with 'gender' is an entirely social creation. Why would Glorianny's hypothetical boy want to wear one? If he was too hot and didn't like shorts, that would be a valid reason, but the fact that thinking about it might make him feel that he was 'in the wrong gender' is 100% because of the messaging from the trans lobby.
I would really like to know what 'being in the wrong gender' means. Feeling you are the wrong sex is one thing. I don't believe that you can change that, but I can understand that someone might think he should have been a woman but is actually a man, or vice versa.
'Being in the wrong gender' just doesn't make sense though. Gender is not fixed. Men wearing a skirt is, as we have seen on this thread, normal in some parts of the world, and as 'occasion' wear in Scotland. Pink used to be considered a boys' colour. Pastimes like knitting were (maybe still are) considered male skills in some places. Gender changes over time, too. 50 years ago it was very unusual for women to have tattoos, or drink pints, but it's not now. So yes, 'gender' expectations exist, but they are not something that you 'feel' - and if you do 'feel like' knitting, wearing pink, or getting a tattoo, there is nothing stopping you from doing so. You don't have to 'transition', and there is no 'wrong gender'. If what you do is against the grain, you might stand out, but it doesn't mean you need to bind your breasts or take hormones.
Also, many young people want to stand out - it's part of growing up. So I'll ask again - what does 'being in the wrong gender' mean, and why would a teacher wearing a skirt be helpful to a boy who feels that he is 'in the wrong gender'?
