Are you arguing that women actually do understand what goes on in guys' minds. That seems to be the only assumption (about women) Neville was making- that they don’t understand what goes on in guys' minds Seems fairly spot on to me.
Women are not mindreaders and there is numerous evidence- anecdotal and non anecdotal- to prove it. And women do act like they understand what being a male is like even though, oftentimes, they don’t.
The fact that a trans woman says “yes this woman is 100% correct about how men think” doesn’t make it true any more than a red pilled trans woman saying “being a man is harder” makes that true. The men I’ve known/met have not acted this way.
The overarching point, that women claim to understand the experience of being a man despite never living as a man, rings true since women often talk about what being a man is like when most of them have absolutely no way of knowing.
