The irony is that we had a babysitter who was a hardcore libertarian and she hated AOC too, and kept on telling me how stupid she was; before that I only thought this hate is a culmination of male misogyny.
But it's objectively amazing. People insult her education? She went to Boston University FFS!
People insult her intelligence? She murders these old men with words as a pastime.
On a scale she counts as stupid, where would those stand who are outwitted and humiliated by her?
I know nothing of Twitch and gaming in the 21st century, but my wife (then girlfriend) used to join our LAN parties. Anytime she delivered a kill on one of my hypermasculine-only-by-my-own-perception buddies in CounterStrike, the guy would throw a fit and we would have to pause the game because all of us are rolling on the floor (except for him).
Re your babysitter, I'd argue a case of internalised misogyny, plus a discommoded sense of unsettled unease (who can a white woman who has already internalised misogyny look down on - in a way that certain sections of her society will readily recognise and applaud, - but a black woman?)
And, if she was a woman of colour, well, there is a lot to unpack, but teaching those who have been historically oppressed, to take on - and internalise - the shame and self-hatred of institutional and societal disapproval and dislike and discrimination, is an excellent way of enforcing and perpetuating such cycles of pain, and endless petty humiliation on those already doubly discriminated against, and oppressed.
As for racist (and sexist) white men, I suspect that she - by her very existence (female, fearless, formidable, fiercely intelligent, accomplished, ambitious, articulate - and worse, a woman of colour, someone who by definition is supposed to be lesser by every measurable criterion) - threatens them to their very core, in ways they can barely begin to adumbrate, let alone recognise, or acknowledge.
