It’s clear to us where he stands and what he believes, which is that trans people aren’t who they say they are
Pretty sure no one is denying that Fox and Owl are, y'know, Fox and Owl. It's more a case of disagreeing with what they say they are.
So are those two hypothetical men suffering from the same condition, just to a different extent and with differing abilities to process it in a psychologically healthy way, or are these totally different and unlinked?
Of course they're linked; they're both instances of men internalising sexist stereotypes about femininity and failing to adequately separate stereotype from biological reality. Standard bloke stuff, in other words.
Plenty of difference too, obviously - the latter group are likely to have faced rather different behavioural policing from their peers, and I'd charitably call them confused and in need of feminist consciousness-raising rather that actively malevolent. But at heart it's sexist stereotypes all the way, regardless of whether it's a case of getting off on the shackles of our oppression or just happening to like stuff that our society codes as pink.
