That's a bona fide genetic trait that, for the most part, appears in one 'race' but not the other.

What you're referring to here, which is quite separate from the other bit I quoted, refers to ethnicity, not "race." All "black people" (a race) do not have a propensity for sickle cell. See: black people from south america, indian subcontinent, australia.
"African ethnicity" is a thing, "black people" is not.
