"were eventually found and a confrontation ensued - it's really important to state that the majority of the confrontation happened not between the TERFs and trans people, nor between TERFs and even the Bookfair Collective, but other people there."
A member of the Anarchist Collective organising the event was described as;
"simply trying to move them out of the building, and particular out of the way of the disabled access lifts."
... when one of the anti-trans "feminists" was reported as calling the hosts "fascists", it was clear that this individual;
"was escalating the conflict with any and everyone there, it was about to turn it physical."
and so this member of the Anarchist Collective (who is cis, incidentally, not that it really matters);
"tried again to move her out of the building because a fight in the school could lose the Bookfair the venue in the future, at which point the TERF in question with the rolled up remaining leaflets and newsletter from the Feminist Library (effectively acting as a rolled up newspaper) proceeded to hit her in the face."
Obviously at this point, having apparently harassed stall holders and physically hit one of the organisers;
"there was enough cause for them to be thrown out and kept out."
"needed to decompress outside for a bit herself"
... with my witness who then reported the following
"and when we came back to the building, ANOTHER confrontation had started, which involved someone from the feminist library."
My informant then reported that they didn't see most of the second confrontation, although someone else has reported that a man with a shaved head punched a woman who had objected to the presence of TERFs at the event, but they do report that;
"the number of trans people involved was minimal, it was almost entirely random people who simply wanted the TERFs out. Much as I suppose I'm grateful for the fact they stood up to transphobes, they did so in the way of disabled people simply trying to get out. We were there, hoping to see the situation de-escalated, or at least moved outside, but to limited avail."
One of the TERFs had reportedly claimed to have been a victim of "violence against women" although my informant said;
"what she meant is still anyone's guess. Nobody touched her when I was there. It was simply a large standoff as far as I saw between TERFs and others. It was almost entirely cis people."
They said that these anti-trans "feminists" seem to have the ability to;
"accuse anyone who opposes them of being trans women. And anyone who opposes them of being a "trans activist""
"The "trans activists" were exceptionally few and far between - it was largely a bunch of cis folk who didn't want bigots at their Bookfair."
In my opinion this all seems to suggest that there were anti-trans feminists using what was otherwise a peaceful event, that the organisers had worked hard to make peaceful, to stir up transphobic hatred, and that those present to enjoy this event did not want such people there. It also seems to me that this group are trying to concoct a story that attempts, falsely, to blame trans people for this incident when all the violence came from non-trans people, including these anti-trans "feminists" themselves.
