It's long but I thought I'd give it a bit of a watch since I've heard so much about him. Initial thoughts are - he's not as clever as he thinks he is. Questions he doesn't like he closes down with a bait and switch answer or a terrifying Paddington stare. Comes across as a bit of a plonker. With absolutely no humour. Helen Lewis did a good job I think of not getting annoyed although he is so bullet proof there's almost no point in the discussion.
His basic thesis (if I understand it correctly) is that society is not shaped by the patriarchy but by competence. So the reason men are scientists and women look after babies is that they are better at these skills respectively. There is no such thing as the patriarchy.
There is a good bit at about 1.05.40 where she asks him why women change their names on marriage if not to symbolise their transfer from one man to another and he says - ugh, Margaret Atwood is an idiot.
