I stumbled across this video of a discussion held by the Free Speech Union. It's an interesting topic that covers a lot of ground. It contains some excellent material from Alice Sullivan and I was particularly taken by Alan Sokel's analysis of how and why GI has got such a foothold in academia.
He starts talking about it at around 30 minutes. He talks about why middle class white academics are drawn to GI as a means of discounting and ignoring and sneering at the views of the vast majority of ordinary, non-academic working class people. He sees it as the ideology of the left-wing professional and academic classes who can congratulate themselves for being deeply concerned about the most marginalised group in society while proudly riding roughshod over the rights of women and others. I think anyone who's been following the Jo Phoenix ET will instantly hear the voices of Jo's critics when he talks about the class issues. I think it's also closely related to Brexit and the way the Brexiteers were portrayed.
Nothing that hasn't been mentioned here before but expressed in a way that I understood it clearly.
