You're claiming that because a change of X is negligible, it must mean that a change of 1000000*X is also negligible. As for my first link - I couldn't find where it showed that, and even if it did, it doesn't follow that the differences are negligible (to whom?) [1]. Why does Africa having a lot of genetic human diversity, make those differences negligible? [1] Especially since Africa has two completely different populations due to the barrier of the Sahara - of course the difference between Europeans and Arabs are smaller than between Arabs and Namibians.
