Giving in to people who are truly unreasonably offended (by proxy, for social validation, and so on) rewards and incentivizes the behavior, and in fact I believe you have an ethical obligation not to allow people to do this. Promoting antisocial behavior is antisocial.
How do you benchmark different ways to interact with employees? Neural networks are somewhere between opaque and translucent to inspection, and your only interface with them is language.
Quantitative benchmarks are not necessary anyway. A method either gets results or it doesn't.
