well, I am a biology teacher in a secondary school, teaching sex, puberty and reproduction at KS3, and hormones of the menstrual cycle at KS4.
I teach there are two sexes, male and female.
The trans question always comes up. I tell my classes that a man can be a transwoman. But they cant be a biological woman. I tell them to be kind and fair to everyone. I stamp down hard on any homophobic or transphobic use of language.
But when they come in with their stories of a man who has given birth, or similar, etc, I just say no, a transman has given birth, not a biological man, and if I am further questioned, I just explain that anyone can be any gender they choose, and no clothing or style of behaviour is entirely make, or entirely female, but you are the sex you are born in, and that cant change. When asked about male brains in female bodies, etc, I just say there is no such thing as a male brain.
I find the brain thing the most infuriating - we teach our girls that their brains are just as scientific, and mathematical as boys brains, there is no difference, beyond societal conditioning, then some idiot in the PSHE department goes and muddies the water, by claiming, totally unscientifically, that there is some sort of vague, mythological difference, that no one can name, measure or see on a scan.
That is what I teach. ANd yes, I have been prepared to lose my career over it. I equate being expected to teach that you can change sex as the equivalent of the teachers being told to teach Nazi race science; Lies, being told for political reasons.
However, being prepared to lay down my career has never been called on, as no teacher in any of the science departments I have ever taught in has ever contradicted me.
Some of the woke deputy heads in languages though....
