My recollection is there were lots of feminists doing amazing grassroots things around 2017/2018.
Indeed there were, and many came out of FWR (eg Fair Play for Women, Mayday, Man Friday)
The Julia Long/Venice Allan/Maria Macauley protest sticks in my mind.
It wasn't a protest, it was a rendezvous prior to a WNTT event.
An event in Bristol called "we need to talk" where women were terrified by TRAs(https://www.theguardian.com/commentisfree/2018/nov/26/trans-rights-protest-gender-critical
WNTT at the Jam Jar. Where KJK spoke for the first time.
There was an amazing woman, I can't remember if we found out who she was, that signed up for her local pool as a man and went to male only sessions in her cossie and flowery hat.
Amy Desir, which resulted in the formation of Man Friday, and the first Hampstead Ladies Pond protest at the men's pond.
Sometime around then KJK got arrested and it came out she was Posie Parker on here. And she did the billboard thing.
Her identity was never a secret, she was speaking as Posie Parker from the start.
Then (I think) this all amalgamated around WPUK and events where women were talking about what happened to them. There was one in the HoC that I remember.
WPUK was formed after and in response to the assault of Maria at speaker's corner. Venice Allan was the instigator of the first HoC meeting.
Before all this there had been RadFem events at Conway Hall which were the precursors to the later meetings/events concerned about the conflicting women's/trans rights stuff.
