“Sexism” is an explicit or implicit belief or practice that qualitatively distinguishes or values one sex over the other. This doesn’t mean that there are no differences between the sexes. Nor does it mean that these differences are insignificant. They are very significant! It means that the differences are valuable, and when all the differences are added up on each side of the male and female ledger, the quality-sum and value-sum at the bottom of the ledger is the same for male and female.
