ums and errs about race, really all that matters is people can be sorted by even a layman and if they produce the same phenotypes in their offspring. Doesnt really matter if race meets your specific standard of taxonomic significance or "meaningful difference" to count. What matters is if it is something real that people recognize and we can study the variation of superficial and non-superficial traits with.

Making implicit classifications but not wanting to explicitly call it race. It is a weasily definition because it's some standard which cant be defined. Can always be said, it isnt enough. What matters is if race is recognizable and sees a reliable average variation of traits we can study, not the sociological consequences but if it describes something real.

What it boils down to practically
----------------------------------

if they are recognizable, they cluster

and when they cluster, they turn on each other

ESPECIALLY when there's an IQ gap because the low average group believes it's being oppressed
