The Rand (Paul or Ayn) philosophy, by putting private property rights at the same level of human rights, equates the status of things with the status of human beings. But people are more important than things.
Some will argue, as many have, that Rand Paul's comments about Title II of the 1964 Civil Rights Act were consistent with his libertarian principles. However, freedom-talk without justice-talk is empty and, potentially, dangerous.
Liberals find the Pauls attractive because, like John Quincy Adams, they believe "America does not go abroad in search of monsters to destroy." Unfortunately, the Paul philosophy precludes looking for them at home as well.
The problem with Rand Paul isn't that he is a racist. It is that he is a fool. The upside is that Paul's primary victory will ensure that, if nothing else, the Kentucky race will continue to provide ample political fodder for the rest of the year.
As a youngster, I remember seeing a sign in a store window that said: "No Dogs, Jews or Negroes Allowed." Rand Paul, acting on lifelong family principle, would have the government do nothing to stop that.
