Equalities, diversities, and other twaddelties
Friedrick Hayek, quoted in an article linked by Tina Trent:
“From the fact that people are very different it follows that, if we treat them equally, the result must be inequality in their actual position, and that the only way to place them in an equal position would be to treat them differently. Equality before the law and material equality are therefore not only different but are in conflict with each other; and we can achieve either one or the other, but not both at the same time”
Obvious, really, though not to people who send out questionnaires demanding that we "self-identify".
