Sometimes it seems that the beau ideal of many conservatives, as well as of many liberals, is to put everyone into a cage and coerce him into doing what the conservatives or liberals
believe to be the moral thing. They would of course be differently styled cages, but they would be cages just the same. The conservative would ban illicit sex, drugs, gambling, and impiety,
and coerce everyone to act according to his version of moral and religious behavior. The liberal would ban films of violence, unesthetic advertising, football, and racial discrimination,
and, at the extreme, place everyone in a “Skinner box” to be run by a supposedly benevolent liberal dictator. But the effect would be the same: to reduce everyone to a subhuman level and to deprive everyone of the most precious part of his or her humanity—the freedom to choose.
— Murray Rothbard explaining how conservatives and modern liberals are essentially the same creature.
