Exactly, I was just gonna say this - seems to be a US MAGA "thing" about women they don't deem 'feminine' enough.
It's absolutely batshit. Brigitte Macron is obviously a woman. It's really not difficult to tell
I don't disagree that the origins of her relationship with Macron are highly questionable. Separate issue entirely. It doesn't make this sensible or even rational. And I've no doubt they've only reported it on the BBC to try to link it to the trans thing ("this is what those nasty terfs who are all funded by MAGA want to do to you all - aren't they evil and batshit?")
