[TFA quoting some scientist:] "it was based on the belief that some humans are genetically inferior"

I thought some members of a species being genetically inferior to others was the principal tenet of evolution. Are humans somehow exempt from this?

Inferiority is meaningless in genetics. Evolution randomly selects with a random statistical pattern that prefers individuals who are most able to survive and reproduce in their particular niche , a notion that has minimal relevance to human society, and does not correlate strongly with "superiority" as defined by human social groups. Example: evolution would reward a poor prolific con artist rapist far more than a strong rich asexual genius.
