Wilhoit’s Law:

Conservatism consists of exactly one proposition, to wit: There must be in-groups whom the law protects but does not bind, alongside out-groups whom the law binds but does not protect.

-Frank Wilhoit (the composer, not the Ameican history scholar)

Domenico Losurdo really explores this contradiction in Liberalism: A Counter-history. All the big liberal thinkers in the 18th and 19th century loved to preach about “freedom” and “liberty” and whatnot, while defending the necessity of chattel slavery.
Really interesting read, would highly recommend.
