... if all non-Africans are a subset of Africans how can we all be separate races?
... If race exists all non-Africans are subsets of the greater African race, at least thats what science tells me.
First, it appears that your "science" is based on disproven communist theories.

So basically, we must all believe a disproven communist theory, or believe that "Africans" are the "greater" 'race'?
How very racist of you.
Fact is that about +90% of the population readily recognizes 'race'.
Why is it that your own eyes don't register clearly observable, biologically inheritable traits?
Could it be that you do actually see these traits, it is just that you wish for them to not exist?
That would make sense if you are indeed a genocidal racist.
Another clearly observable pattern is that despite generations of pro-miscegenation saturation of popular culture... people still vastly prefer to mate within their own 'race'.
Why would this be if 'race' does not exist?
Fact is that human breeding patterns are not as random as mixed-race supremacists would like us to believe.
It is now proven that there is a serious difference between African and Non-African genetic makeup. It appears that non-African populations do have a bit of Neanderthal(commonly thought to be a different species) genes.
Not that the Lysenkoistic assimilation theorists will even acknowledge these sort of politically incorrect facts.
They will probably prefer to blabber on about "social" impacts of such information.

A result: 1 percent to 4 percent of the genome of non-Africans today is derived from Neanderthals, say scientists
If one observes breeding patterns, this differentiation makes sense.
(Over) simply put, Asian and European populations tend to interbreed successfully with eachother more often than with African populations.
If you really want information, try examining scientific data that is not published with the express purpose of enforcing "social theory" or "African supremacy".
Maybe even refer to data that is collected with the actual interest of helping people, instead of racist commie quackery?
