I stopped reading it about three times. I didn't mention the lack of definition of racism but that's a red flag as well. If I were not familiar with fascism from his writing I'd assume fascisms key attributes would all be related to race and sex. When your read the current popular definition of fascism it is far away from libertarian ideas he counters in this post. The use of the term is the biggest mistake in this post

It is fair to say the libertarian ideas do not fix human hate. That they are not an answer for the ills of discrimination. I haven't heard an argument that they are. What I have heard is that decentralized society would lead to more diversity and less violence.
