How is this alloeed to be so in institutions of learning and in research? Belief over material reality. Will universities tackle this?
No, is the short answer to that. I know, it seems perverse and illogical that the academy would not recognise or fight spread of an ideology, especially if it was based on untruths.
I think there are a few contributory causes. The first is that the universities are beholden to students because that is where they get their income. It has become very much a consumer culture. In the past, academics often didn't really give a toss about their undergraduate students. Now, everything is focused on student experience etc and a complaint from the student body would be taken seriously.
Secondly, there has become a tendency to simply no-platform certain views and gender critical ones are definitely among the silenced voices. Germaine Greer was famously no-platformed. Julie Bindel similar. Their views are simply not allowed to be heard. This means that they can neatly be portrayed as extreme, hateful and radical without anyone actually hearing them to make that assessment.
Thirdly, many many academics are now precariously employed, seeking renewal of contracts year on year. It's simply not worth the stress and hassle of what would happen if you stuck your neck above the parapet. The ones that have- Rebecca Reilly-Cooper and Julia Long for instance appear to longer be employed by their previous institutions as their profiles have been removed (Warwick and Anglia Ruskin). That might be a coincidence- Rebecca went on maternity leave last year and may be taking more time out, but no doubt their lives were made difficult by what they were saying. Unless you are very very senior, it's not worth it. Sheila Jefferys is an academic but a retired one, so no backlash from the university to worry about.
Fourthly, many leading academics (readers and professors) are vocally pro-trans. Professor Alex Sharpe at Keele is a transwoman. She wrote a scathing blog about Rebecca R-C's gender-critical work. She is obviously a lot more influential than Rebecca so more people will take notice of her.
So yes, it is very much a question of being silenced and keeping your head down. I am not even radically gender critical in that my views have been disagreed with on here (that is NOT a dig at anyone by the way, just an observation), but they are definitely more critical than the mainstream. But I can say hand on heart that it's not worth it for me. I would make myself virtually unemployable and I don't have the gravitas of more senior colleagues. I follow Karen Ingala-Smith and Women's Place on Twitter, but that's as far as I dare go. I can see that a few other colleagues follow them too so I think they are secretly GC, but it's not something we discuss.
Oh and fifthly, we have trans students whose welfare we have to consider. As critical as I am, I would not be prepared to deliver a lecture where I know that a member of the audience would find it upsetting (plus I would be hauled up on a disciplinary).
Hope that answers some of your questions...
