because in person everyone understands that you don’t insult people you’re trying to work with
Allowing casual race-based insults is bad, even if they’re directed at white people. We know this is bad because no significant in-person org allows it. Allowing it here is the definition of extremely online behavior.
People aren’t getting called cracker in real life, not because its such a terrible insult, but because that has just never been a thing that happens, because white people are not oppressed in any kind of racialized way. I think its an extremely silly thing to be concerned about.
