I'm not sure I can get overly irate about this.
Is it wrong that Eton has a Feminism Society - that's great surely? It's not that boys went to a girls school to talk at them. It was two groups talking on 2 topics, with the girls happening to host. I assume they alternate.
The text says that Eton boys spoke "gender theory, and how one’s gender can act as their identity, with the perception of transgenderism gradually being more widely and positively perceived in today’s society."
We can't see what was said but phrases such as 'can act as their identity', 'the perception of transgenderism' give room for a diverse discussion. I'd also like to think that the girls picked them up on any relevant points.
Glosswitchs's thread is just a study in inverse snobbery - as is Julie's predictable comment. You can only be a feminist if you're a woman and working class/socialist... apparently.
