I don't think it's really racist, more that the different races in elder scrolls have different values and upbringings.
Imperials favor diplomacy and craftsmanship
Redgaurd society is based more around physical ability
Nords live in the frozen north and, therefore must be hardier in order to flourish in such a harsh climate.
And then there's the matter of the Argonians, the Elves, the Orcs, etc
They're completely different species, not just differing members of the same group (asian, white, black etc) and would naturally have abilities that would differ from their human counterparts.
