The reactions are non-voluntary and humans evolved this way. And since it's in our genes that our women are predisposed to feel like ugly people are genetically inferior, that is enough proof to say that they really are in a certain circumstances, specifically where sexual selection is the deciding factor in the success of reproduction. We live at the times where sexual selection trumps all other factors by a large margin, so people who are not desirable because of things they may not have control of, because they are genetic, they can be called genetically inferior.
