Okay so basically privileged people are fragile and in order to be able to actually discuss oppression we need to mitigate that fragility. Working class people have a grand tradition of affectionately teasing each other. We do this WAY more than bougie people do but we do this not to tear eachother down but to strengthen one another so that we can take it when the world comes to tear us to shreds.
When we tease cis people/het people/white people/men/etc we’re doing it to help them build a callous so that they can actually have a meaningful discussion when it comes time to discuss actual oppression, rather than them feeling injured and huffy.
