I’d say these situations show that we must have more diversity, not less, in all our interactions so that we learn to become more used to differences (insert race/gender/whatever else some people trip over.)
However idiotic it may seem, in a non-safe, litigating environment one can, sadly, expect these knee jerk reactions. The only way forward is to make our society a safer place. This probably relies on all parties becoming more aware of the effects of their actions as well on the receiving side having a buffer and being tolerant such that we don’t get a cascade effect.
Edit: I mean the above paragraph in the sense that just like aircraft investigations are about finding a root cause instead of blaming, discussions should be more about achieving harmony together or to agree to disagree.
