No it's not ok. All people are alike. Better stop dividing them. This will not lead you anywhere. We all living on the same planet.
Their is a thing called subspecies you know that right?
Good luck trying to find a good definition of 'subspecies'
a category in biological classification that ranks immediately below a species and designates a population of a particular geographic region genetically distinguishable from other such populations of the same species and capable of interbreeding successfully with them where its range overlaps theirs
a named subdivision (as a race or variety) of a taxonomic species
"a population of a particular geographic region genetically distinguishable from other such populations"?
That would mean 3 subspecies: 'sub-sahara-african', 'east asian' and 'european'.
The 'overlap' is kind of big. Where do you draw the line?
