I am a Biology teacher and am Gender Critical. I will openly say this to other teachers and SLT if pressed. I will be not teaching children things like 1000 genders exist or that individuals can change their biological sex. I teach students biological fact, not fantasy. Even amongst my own science department, I am a minority voice which is utterly shameful. If you can't rely on science teachers to hold firm then who can you trust? Thing is, I don't even think any of them even believe it. They're just going along with it because they have fallen for the progressive misguided educational view that every student whim and feeling, however irrational, must be placated to or given credence.
I am appalled by the gender ideology going on in schools. It's a massive breach of safeguarding and I will absolutely not socially affirm a child who wants to identify as the opposite sex without firm parental permission. If I am ever asked to keep a secret from a parent about a child, I would seriously consider resignation over it. You wouldn't keep an eating disorder or talk about self-harm or suicide from a parent about their child so why would you keep this from them? It's a huge safeguarding risk. It prevents parents from seeking support and help for their child and needs to be treated like any other mental unwellness. Socially affirming children is not a passive or neutral act. Doctors and nurses have recently been advised they cannot do this either.
I am sick of this capitulation to what is nothing more than a social contagion. Why are teachers so willing to throw away their professional reputation, their integrity and their natural reasoning skills just to pander to a minute minority of the population who will most likely change their mind about it in a few months? It actually boggles my mind so much.
