It seems the ACG's position is trying to do the both sides thing see this statement from 2021:
The particular relationship between trans women and some other feminists has been fraught and has resulted in extreme polarisation, making it very difficult to unite against patriarchy, gender oppression and capitalism. Sensitivity and understanding of the oppression that different groups experience – those socialised as women, trans women, trans men, and non-binary people – is needed in order to move forward.
We believe that it is unhelpful to set up a false dichotomy, as has widely been done, between “feminism” and “trans rights”. These are not struggles inherently in opposition to each other, but which are worth fighting for together, while working towards a wider understanding of both the shared issues and the differences.
We must come together to end all oppression as well as to help create a united working class movement which can effectively challenge capitalism and hierarchical society.

Here the ACG claim trans rights is a class issue on a thinly argued basis :

Of course it is not enough so they have been cancelled. Presumably they were seen talking to some women with opinions, reading Harry Potter or something outrageous.
However good to note not all anarchists are taken in by the sexist neoliberal genderist line. This is a great read originally put out in 2019 as a print anarchist zine by a bunch of anarchist men who knew sexist trash when they saw it and were ready to call it out.
Shit Wigs and Steroids : Anarchism’s (and the Left’s) Tolerance of Delusion
The booklet was put together by a collective of working class anarchists around the North West of England. All of us are men who are against the misogyny and homophobia of the bullshit liberal goons rallying around transgender ideology. We took the approach outlined in the booklet as we are not wankers from the university educated Left, so we are not tamed or muzzled by the adoption of an academic template to speak from. We have been very pleased to see the positive response the booklet has had around Europe and the wider world (especially America, New Zealand, Australia, and Ireland).
This booklet was put together by working-class people amused and bemused by the transgender cult. It will be of interest to those not buying into all this “transgender/crossdressing” bullshit.
It is not written out of ignorance but as a result of considered critical thinking. It is a very sharp critique of the bogus transgender arguments. A hairy bollocked man is not a lesbian, regardless of anyone’s opinion. It’s a man with hairy bollocks preying on the tolerance and gullibility of others.
Being called “bigots,” “transphobes,” and “TERFs” is comical, and it is the best the phoney transgender brigade (and their enablers) can offer up against wider society’s scrutiny.
We make no apologies for our lack of charity towards these misogynistic men’s attempts at censoring considered opinion. To some, being offended is an identity in itself.
