I thought your daughters were going to be teens/20s. I wouldn’t engage with their sexist/ageist rants. They sound too far down the rabbit hole.
If you do want to present something for them to think about:
The Cass report;
Current investigation into Mermaids by the Charity Commission;
Current revised NHS guidelines that are at consultation stage, including the advice that trans for most children/teens is a phase, and not to rush to affirm/medicalise;
Eddie Izzard: 60 year old male who previously claimed to be a heterosexual male transvestite, now claiming to alternate between girl and boy mode, and openly using womens toilets at public events;
Whistleblowers from the Tavistock clinic;
Recent case of female solicitor who had an operation cancelled at a private hospital because she’d requested female only after care;
Male prisoners identifying as women, moved to women’s prisons with often horrific results. A huge number of terrible cases have been recorded in the US.
There’s a thread on here called something like “Things that never happen…..” which details how men in womens spaces have adversely affected womens lives.
Subscribe (free) to Graham Linehan. Daily information about how womens rights are being threatened by trans ideology.
Maybe JK Rowling’s essay explaining her original foray into the apparent erasure of the word women. Not a transphobic word in it.
Maya Forstarter. As a result of her legal challenge to her employers, being gender critical is now a protected characteristic in the Equality Act.
Julie Bindel is also amazing on the whole trans/womens rights issue.
If you want to engage one last time I would select some of the above in written form. Give it to them and say this is why I believe the trans ideology is a threat to the hard won rights of biological women, who had to fight for those rights due to their sex based oppression.I would then refuse to discuss it. Every time they bring it up say I’ve shown you why I feel as I do, so we’ll have to agree to disagree.
I really feel for you. It’s almost cult like.
