It's good you clarified that, because I know black males are never insensitive.
I tease. But I do see the value of being mindful of cultural differences in companies that employ a diverse workforce. No, it has nothing to do with the taste of the orange juice, but understanding where your colleagues are coming from is still productive. The typical employee probably is unaware of cultural differences that might come up with colleagues from cultures they're unfamiliar with. I'm thinking mainly here of cultures that have different values or practices from the dominant culture in the company, like a devout Muslim or Orthodox Jew working for a secular American company.
Though, yes, people who build their career on diversity tend to go a bit further than just preventing stuff getting lost in translation across cultural divides, probably for similar reasons to why brands can't just be left alone.
Diversity isn’t about the color of one’s skin, it’s about what that means when embedded in Western society.
