When I heard of this new book by Johna Goldberg "liberal fascism", I thought it would focus primarily on how the left today suppresses any opposing viewpoints, (in a style akin to fascism). The book may actually be about this but this talk is not. Goldberg describes how early 20th century fascism was actually a leftist phenomenon. Goldberg points out that communism was a world type of ideology whereas fascism had its roots in nationalism, but that in terms of policy, fascism and socialism were very similar.
This talk is in 6 parts and then there is Q and A. I'll provide here the link for the first section. I think a historical understanding of the left's creation of 20th century fascistic movements is important, as it certainly helps put modern liberalism in context.
