The problem is that once you say that something has a strong genetic component, two different genetic groups having the exact same distribution of that attribute would be really surprising.

But while we are fine with different genetic groups having different incidences for hair color, nose shapes or skin pigmentation, and are slowly coming to grips with different genetic groups having different incidences of various illnesses, and sometimes different reactions to them, the idea that different genetic groups could have statistically significant intelligence differences feels wrong.
