Except for the part where it provides an actual workable solution to the problem at hand.

To me this is an argument between completely different mindsets, one that restricts itself to provable facts and one which restricts itself to political agendas. I don't see how the latter can also work in facts. Or belongs in a technical research discussion at all frankly. You want to make laws that force companies to produce identical/equivalent outcomes for every race somehow? Just go lobby for it. Perhaps it's a good idea. You aren't going to reprogram mathematicians to think in political terms instead of mathematical terms.

Even if sincere good faith and he has real expertise is assumed that approach kind of raises several "huckster alert" red flags.

Sure, you can look at it that way if you like, that commonly results in hiring someone to be responsible for D/I without actually making any other changes.

A better response is more along the lines of "Not in MY Army" which makes it everyone's responsibility at every level.
