Oh, that one's easy.

You are entitled to no adaptation from others. Your reactions to their "errors" are your problem, and your responsibility, although of course you can choose to start a fight over whatever you want.

On the other hand, if you do not adapt to them, sometimes they will choose to start a fight over it, or be offended, or whatever. As such, if you want to improve your social outcomes, consider allocating energy to adapting to others.

See? Simple. No centralized decision-making necessary. Each person can ruin their own life however they choose.

This genuinely misunderstands people from internal-only diverse cultures like Mainland Chine and India where they make frequent social faux pas yet are convinced they could never be uncomfortable or offensive to other cultures because "my country is so diverse!". If I had one Euro for each I heard that, I would be richer.

My general rule: If you are from an externally diverse cultural then you need to adapt to non-diverse cultures (Japan Korea etc) or internal-only diverse cultures (South Asia, Southeast Asia). If you cannot adapt to other cultures, then what is the point of working in a multicultural setting?
