Can anyone explain specifically how libertarianism itself is anti-black, or harms black people specifically?
I don't think it's anti-Black, but I think it is very naïve when it comes to dealing with the natural human tendency towards tribalism, and unintentionally or otherwise, opens the door to majoritarian tyranny.
But that aside, I find it bizarre that none of the thinkers I listed above live up to the standards that Libertarianism supposedly preaches. And we're not talking about 19th or 18th century thinkers here (though ironically John Stuart Mill was less prejudiced than Mises, despite predating him by a century,) so being from a different time is no excuse. Can Libertarianism even be concretely separated from these tendencies that seem to have been with it since its origin? Sure, we can think about it in the abstract, but I mean as a matter of really-existing people.
