This is one of the extremely few cases where I have the opposite take from you.

Race is (mostly) socially constructed. Because it's (largely) arbitrary, you start from how the relevant people construct it, no? Where else do you start?

If semi-arbitrary construction A produces bad outcome B, and we now have a different semi-arbitrary construction A', bad outcome B is still incredibly relevant.

Ignoring the parallel is dangerous and dishonest unless you think race is a strong intrinsic biological property as defined in the West these days.

Doesn't call for suspension--that part's silly. But it does call for correction.
