This is true, but somewhere along the line I think there needs to be a normie-friendly version of the argument as a "thin end of the wedge". There are a lot of people who are more comfortable speaking in terms of "culture" and the effect that has on outcomes, and for those people I think the point needs to be made where, even if that is true, you are legally prevented from discriminating based on "culture" if those cultural differences correlate to race.

A landlord was prevented from exterminating rats in a building because it would result in an increase in rent which would disproportionately affect the poor tenants who tended to be non-White.. No sane person looks at that and thinks makes any sense, but that is what the Civil Rights Act and Disparate Impact leads to.

Something has gone badly awry when a city can’t even make slumlords kill rats without fear of a lawsuit.

Reading The Bell Curve can come as part of a later lesson.
