Otherwise known as Lewontin's Fallacy. Race is genetic. If it wasn't then you couldn't reliably predict race from genetic information. But you can. Easily.To your other points, racism (like race itself) is a completely socially constructed, historically dependent phenomenon. Let's dissect what that means:
It's socially constructed because there is no biological basis to race. Ask a scientist. Across all major differing characteristics, major studies have shown that there is more individual-individual variation within a group than group-group variation (with respect to groups of race and nationality, for example).
If you know enough math you may understand this link.. But I doubt you do, or you wouldn't have fallen for the fallacy.
Of course it doesn't say anything about the intelligence of races, but we still shouldn't be spreading obviously false information.
