Lucy Crehan has spoken at ResearchEd!
Other women. Hmm, Becky Allen? Laura McInerney?
Never heard of Bleiman but I’m not English. I’ve seen maths talks by women, and several by Carol Davenport of the Institute of Physics about girls in Stem (boo you say!) so I can’t see that they’re anti women or feminism (Lucy Ryecroft-Smith for maths would definitely challenge that notion).
It seems your favourite, David Didau, is pally with Sabisky

Sabisky was the source of the race stuff that got Didau into trouble.
I think Tom is probably pissed off at people demanding to know why Sabisky had a platform at a grassroots event organised by volunteers when he got hired by Number 10.
