Does it not concern you at all that you have, like, zero ability to assess the merit of HBD claims, and therefore are in no position to reason so glibly and confidently about Alexander's motives? If arguments for population differences are compelling, then all this schlock about suitability to chattel slavery and what have you becomes irrelevant. You imply that Alexander believes the former due to preferring the latter, but that's only a plausible accusation if the former is assumed a priori to be ridiculous. (It isn't; on the contrary, there is no plausible scientific hypothesis that can attribute population differences solely to environmental causes. The entire blank slate case relies on sneering of the sort you do here). I find it strange when competent people get so fixated on flaunting their ignorance.
