It's true there is greater genetic diversity within races than between them, but this does not influence the aggregate differences in phenotype/traits between our categorized groups. If there were no difference, you wouldn't have only certain groups affected by certain diseases-- for example, sickle-cell disease is almost unheard of in whites, but appears in people with African ancestry. That's a bona fide genetic trait that, for the most part, appears in one 'race' but not the other.

Good answer. Especially the part about genetic diversity, sickle cell, etc... Not only does it effect disease but it effects other traits as well. For example, it's a well known fact among lifeguards that most black people sink. Their muscle to bone density is higher than other races which makes them less bouyant.
