we are racist like a fish is wet. it permeates our environment, saturates every crevice. this is not admonition, not a call to shame or guilt. we don't choose our birth. we had no control over the culture we were immersed in growing up, and we literally can't divest it all and come out whole. baseline racism is not a personal character flaw, it's our ethnic legacy.
denial might be a character flaw. not listening. getting defensive, deflecting, whatabouting, white-knighting. (and of course doubling down, but that demographic is probably not reading this.) all the myriad ablative responses that pop out when you take comments on your banal, unremarkable, everyday racism as accusations and not just pointers to stuff you could maybe try to work on.
everyone already knows fish are wet, the ask is to watch where you're splashing.
