OP, you must complain to the Head.
This misogynistic agenda is gaining traction in schools and the tragic thing is that the most enthusiastic supporters are young girls.
Girls are brought up to placate and please, to include and make space for others. The TRA movement preys on this.
Thankfully as a just quit the profession teacher I last worked in a school where no-one had drunk the kool-aid, but teacher twitter is full of nitwits - mainly young female teachers - spouting the kind of groupthink, fact-free nonsense that gets J K cancelled by teenage girls who think they're single handedly saving the lives of oppressed trans people.
Teachers are routinely telling young people that trans people are an oppressed and marginalised group.
Teachers are routinely telling young people that more trans people are murdered/have acts of male violence committed against them than any other group of people.
Teachers are routinely telling young people that trans people deserve equal rights.
The irony is that it is women who are the most oppressed and marginalised, women who are the most vulnerable to male violence, and women who don't have equal rights. This is what the girls in our classrooms need to hear.
There are no rights trans people don't have. There are many rights women don't have. Including those the TRA lobby are removing from us.
Girls need to understand that transmen are not asking for the same things transwomen are, and they need to be taught the connections between that and deeply ingrained misogyny in our society. The saddest thing is that so many women have internalised the patriarchy to the point where they don't even see what the problem is.
I would like to add here that I feel deeply sorry for transpeople who are just trying to live their lives in the way that makes them happy, and who respect the fears and concerns of women and want to ensure women have access to safe spaces. I know and acknowledge that TRAs do not represent the majority of transpeople. Transpeople need to have every right to be able to live their lives free from judgement, persecution and oppression - but the way to do this is not to erode the rights of others, nor to persecute others who don't want their identities removed in order to validate those of transwomen.
A truly balanced lesson on this issue would be this teacher showing her class the death threats J K Rowling received from these so called oppressed transpeople who are made 'unsafe' by her factual assertion that the realities of biological sex cannot be wished away. Interesting that so many transwomen who are part of this bullying brigade suddenly want to reembrace their penises when it comes to dishing out the rape threats, isn't it?
Anyway, I'm rambling in my fury. Get onto the Head. This needs to be challenged every time it happens. Teachers are not allowed to present one sided arguments on political issues anyway, so this teacher will need a reminder of that regardless of the Head's views on the trans issue.
