change has consistently come from the left and from feminists working with systematic theories about patriarchy and thus developing strategies of resistance
I agree with you about a lot @YellowAsteroid (although not about the letter), but this paragraph made me snort a bit.
The academic researchers and professional opinionaters, on the one hand, and the on-street/YouTube polemicists, on the other, already agree about the ideology: they differ only on tactics.
(And yes, the polemicists may attract all sorts of fellow travellers, but they're also raising consciousness (sorry!) in voters, which politicians do care about.)
As alluded to by @TempestTost both factions are dwarfed by the majority GC contingent, made up of ordinary people who can't or won't speak up.
Meanwhile, the Establishment takes no notice, or rolls its eyes and mutters 'the transphobes are banging on about not being Nazis again. Well, they would say that wouldn't they?'.
JCJ is trying to do a good thing - to get the entrée with government decision makers - in the wrong way (and she's the wrong person, as is PP).
The TRAs did a bang up job of worming their way into the corridors of power. How can we match that? How do we get Sir Keir to invite Rosie Duffield into his office to talk about what he can do to help? Answers on a postcard....
