“Nature vs Nurture” usually means “how they were born vs what happened after,” so one is biological and one is biological + social. Yugopnik is being concerning here, but he isn’t actually specifying what he means on this axis because both can be biological.

Edit: but he isn’t ruling out nurture, as much as I would hope he was past ascribing these problems to “genetics” as a Marxist . . .

Rephrased what I said to be more technically accurate to his bad take
