I wouldn’t worry about it.
What you should be more worried about, is the inevitable result of globalization/multiculturalism leading to multiple sub-species of humans occupying the same ecological niche.
By the principles of evolution:
This will either end in genocides (by natural selection or otherwise) of the less evolutionary fit sub-species,
or a natural separation of ecological niches along racial lines, either geographically through forming nations (balkanization), or functionally through class division (racial segregation).
I don’t like any of these outcomes.
