Casual racism is calling a black student “loud”, “obnoxious”, and “troublemaker” and a white student who acts a similar way in class “silly”, “funny”, and “class clown”.
Casual sexism is calling a cis female student “loud”, “obnoxious” and “bitchy” and a cis male student “social”, “funny”, and “someone who participates in an engaging way”.
I feel like the balance of sexism tends to be against men in schools. At least through high school. I haven’t seen many...
(also assuming someone is cis makes me sigh but i’ll take the rest)
