Sadly, this is not true
Yes, yes, race science etc, ghastly stuff. And yet:
Does that mean race is a biologically meaningful definition? It does not. Race as we currently use it is a socially constructed idea, but one with biologically meaningful consequences, such as in healthcare where many disease outcomes are significantly worse for racial minorities. The impact of disease correlates significantly with socioeconomic factors, primarily poverty, and in our society racial minorities are mostly in lower social strata. Black and brown people endure worse medical outcomes not because they are black or brown, but because of this fact. The science very clearly evidences this, and no amount of cosplay race science – or human biodiversity, as they euphemistically brand their propaganda – can debunk it.
No, that’s going too far in the opposite direction. Thalassaemia in Med littoral derived genetics, sickle cell in West African (both, likely, deirved from beneficial malaria resistance), Tay Sachs in Ashkenazi, booze and lactose intolerance in East Asians, propensity to diabetes in Pacific Islanders and on and on. It is not – simply not – true that health differences are reliant solely upon socioeconomic status. But that’s what he’s trying to say here. A more equal society isn’t going to do away with any oof those things I’ve mentioned there now, is it?
