Unfortunately significant portion of my friends seem to think that saying racist, sexist, fascist things and laughing is funny and quantifies as a joke. Basically how do you get shithead white suburb kids to care about struggles of people and not play that off as a joke?
If you're trying to keep things light without starting a discussion, just say some like "damn that's so edgy" or "calm down Hitler". It gets the point across without bringing the mood down too much
I actually want to be your friend
