EDIT: It's not racist to highlight that different races have different genetic traits and that sometimes these traits can directly translate to pros/cons of biology developed based on specific factors over time.
It
literally is. The concept is called
scientific racism, and it has been
thoroughly discredited by modern science.
That's not to say populations aren't biologically different from one another; but linking that to "race" is fallacious, because "race" is not a biological or genetic reality. Examining the genetic differences between populations in different regions reveals not clear delineations but rather a continuum, and any attempt to separate out such populations into different categories is by its nature arbitrary.
