See, I look at what you wrote and draw the mirror-image conclusion: "Here is a person who would prefer to shame others for being 'impolite' than let them say out loud what is obvious to literally anyone."

The fact that the situation is as GP described is undeniable. But there can be reasons why things are this way that extend beyond what the racists of yore believed about genetics. Most obviously: Not all subgroups of white people are equally represented in tech either. (When was the last time you were in a team where the majority hailed from Appalachia?)

But actual investigation and remediation can't begin until we can first point at reality and describe it as it currently is.
