Fujoshi discourse is one of two things:

mob-zombie:

a) TERFs attempting to dismiss the identities of trans men by claiming them to be straight women with a gay man fetish.

or

b) young fujoshi hitting their ‘not like other girls’ stage/young trans men hitting their ‘aggressive misogyny to distance themselves from the gender they may still be socially perceived as’  who don’t mind being racist and appropriative to do so.

There can be mixes and people jumping between the two categories, but they almost always fall in those categories.

The only outlier is c) homophobes who’ve realised that can hate on gay people and gay content as much as they want as long as it’s layered with enough social justice buzzwords. Easily confused with A) but somehow rarely noticed by the either of the other two groups no matter how much they post/reblog publicly about actively hating gay men/talk about how gay men are sinners/demons.
