When the Civil Rights Act of 1964 was passed, there were a few people like Barry Goldwater who opposed it on principled libertarian grounds. These were not southern rednecks or Dixiecrats, and they were glad to see the end of Jim Crow. But they were concerned about giving the state a new power to dictate who people have to do business with. Jim Crow had violated the freedom of association in order to make racial integration illegal. But the new system violated the freedom of association in order to make discrimination illegal.
The current argument about gay marriage vindicates those concerns.
