Apparently, TW only adopt typically female mannerisms/clothing/accoutrements (e.g. sexist stereotypes) so that we 'recognise' them as women. But we (T*s) are never satisfied because, when they don't, and these unfortunate women who were born into male bodies choose not to adopt these sexist stereotypes and wear the clothes/maintain the appearance most typically associated with their sex, because that's how they prefer to present, we say they're not women either because they 'look like men'. They can't win. Apparently.
Apparently, we can't have it all ways. Either being a woman is about the clothes you wear/interests you have (the stereotypes) etc or it isn't.
When I point out to him that, actually, it's just about the biology. And that most women don't 'feel like women' - that is just proof that we are c** and that only those whose gender is incongruous with their sex are aware of it.
And when I point out that that doesn't matter and that sex is the only thing that matters because that refers to the needs we, as individuals have, based upon our sexed bodies - for social situations; medical situations etc that's just because we are being overly simplistic. I think these are the times though that he gets close to 'getting it'. But he can't let himself get it because that's Wrongthink.
Rather than see man/woman as biological categories, my son, and others who hold the same views, see them as social categories.
And, if you accept man/woman as social categories rather than biological ones, actually, the argument makes sense. Except that they are not social categories because man = adult human male and woman = adult human female.
But that's reductive and unfair on the women who are born into men's bodies and the women who are born into men's bodies. And who are we to question other people's experiences of reality.
And so we arrive back at square one.
