I’d like to understand your point of view.

To say that there is more variation within a race than between races when examining a single gene at a time does not support the notion that there are black Africans “much more related” to white Europeans than to each other.

The fact that there is more genetic diversity among black Africans than among white Europeans doesn’t support that claim, either.

There is no single gene that determines skin coloration.

You are right insofar you allow yourself to be imprecise and make sweeping generalizations. Of course a light skinned person is far less likely than a person with darker complexion to have ancestry who lived ca. 2000 years ago in for example south africa, but there's a whole lot of leeway in those 2000 years and at the very least its ignorant of e.g. India. And then the question is whether the question mattersat all.
