Wow, it takes a special kind of ageism and racism to render invisible leading figures in the gender critical movement.
Do you actually think that eg Keira Bell or Raquel Rosario Sanchez count as old?
Or is it just that your racism and ageism means you ignore their existence because it doesn't fit your pet theory?
Yes, some younger people - particularly young men - support theories that allow them to punch down at older women. And yes, there's nothing like experiencing misogyny based on one's biological sex such as discrimination due to pregnancy or maternity to make one realise that biological sex matters, which very young women are less likely to have experienced yet.
But the idea that it is a battle of young v old sounds a lot like David Lammy and his 'dinosaurs' comment - and we all know how successful that was as a form of attack. 
You'd have a hard job explaining to me why so many leading lights on your side of the argument like Peter Tatchell tend to be older - and men.
Why is that? And how do they fit into your nice little battle of the 'virtuous' young versus the 'past it' older generation?
