Idk, I acknowledge it must be a pain in the ass to know whether you can call someone the equivalent of "dude" or not, but I feel like that one's fair. When you recognize something utterly mundane is a high insult in someone else's culture, you kinda stop using it towards them unless you intend the insult.
I sure as shit wouldn't just drop the honorifics with a middle eastern/asian stranger or walk around their house in street shoes just because doing so is unremarkable where I'm from.
