quote: ‘Since egalitarians begin with the a priori axiom that all people, and hence all groups of peoples, are uniform and equal, it then follows for them that any and all group differences in status, prestige, or authority in society must be the result of unjust “oppression” and irrational “discrimination.”

There's a lot of red-herring straw man arguments in just that one paragraph which totally misconstrues the liberal view of egalitarianism and equality.

It appears much of his views are influenced by Russell Kirk who was influenced by Edmund Burke, a lot of which follows Plato in that "class" or hierarchies are not only inherent in humanity but necessary to keep order.
