autistic parent (K1 11/18, K2 11/20, * 10/22, K3 10/23). agender (and white). writes (textbooks and book reviews). teaches math (to engineering students). likes science fiction (especially worldbuilding).
One thing the recent sexism discussion made clear to me: many people, when asked whether they witnessed sexism, talk about isolated sexist *remarks* they witnessed or didn't witness: catcalling, fuckability scoring, demeaning commentary about body weight.
But sexism is *structural*, and witnessing sexism also means witnessing mansplaining, almost exclusively male engineering classes or upper management ranks, gendered clothing and toys for toddlers, parenting advice for "moms", and much more.
