In computer terms, their hardware (race) is essentially identical in capability, disregarding minor individual defects. At the software level (culture) there is tremendous variance.

I often wonder what percentage of these disagreements are because of a misunderstanding of what level of the system is being discussed &/or that fact that substantial numbers of people don't/can't differentiate between race & culture.
