Have TERFs ever been accepted in anarchist/""anarchist"" spaces where you live? My experience as a trans man in Mexico who went through the TERF wave from around 2019
I recently saw a Facebook post from a self proclaimed "anarchist" TERF who just repeats the classic TERF speaking points: "Trans people are erasing women" "Trans women are perverted men" "Trans men are manipulated lesbians" "Gender is a purely biological reality with menstruating people being victims and penised people being natural rapists", etc...
Luckily most anarchist communities here have entirely driven TERFs out and queer anarchism is one of the predominant movements inside anarchism right now. But it hasn't always been that way
Around 2019 there was a huge feminist wave all over Latin America. Here in Mexico feminist protests became massive. Most of the women who participated were just normal people who wanted very basic rights which didn't (and still don't) exist in Mexico. The movement seemed to be a response to how normalized gender violence was (and still is) with society victim-blaming women for rape, femicides, etc... 99% of the time.
However many of the "leading voices" in the movement (groups such as Brujas del Mar) were outright TERFs with ties to right-wing parties which were dismissed as conspiracy theories back then.
These groups were also highly eurocentric and marginalizing against poor and indigenous women. They almost entirely based their feminism on white European/US writers and portrayed themselves as 17th century white/US/European witches, while ignoring we have indigenous feminist writers and witches here too. Class or race oppression was completely to be dismissed in the name of "sorority"
I still identified as a cis woman back then and I remember receiving highly racist and classist comments inside of those spaces (while being accused of breaking sorority when denouncing them), not to mention the hate I received when I started to identify as NB and then as a man.
To the point of these post, many of these TERFs proclaimed themselves as anarchists and were pretty much accepted in anarchist spaces, there were many incidents of self-proclaimed "anarcha-fem" black blocs beating down trans women during protests and seemingly focusing on attacking trans women over anythign else (Look up Mikaelah Drullard and her incident at an 8 March protest for more info on this kind of stuff)
Most anarchist communities broke down during the pandemic and took a lot to rebuild afterwards. Fortunately queer anarchist highly participated in the rebuilding while most TERFs took their masks off and became downright conservative afterwards. Unfortunately TERFs are still highly relevant and accepted in academia and universities such as UNAM where "queer-patriarchy" and "erasure of women" being common themes in talks and classes promoted by the authorities. (You'll never see the TERFs giving these talks and classes denouncing gender violence from the school authorities....)
