It's actually a remarkably good one. If we continue to mix for several hundred years more then it won't be. For now, it is.

Because of the founder effect, white people have way lower genetic diversity.

It's like we've split the encyclopedia into three books: A-S, T, and U-Z.

Africa's higher human diversity is mainly in low-population groups like the Khoisan. The big groups are not nearly as diverse (although they do carry some Khoisan genes, for example).

This isn't true.

[polotics]

Indeed really not true. For example: I am quite mixed, declared my own race on an unclaimed spot of non-scientific identity-formation, and despite what some would say and discounting any possible future irradiation, my genitic diversity is absolutely zero ;-)
