I think this is generally true, but do you think that fascism might be a historically contingent politics, as dead as Stalinism in a practical sense, and equally unrevivable? Fascism proved to be quite politically sterile in the nations that were spared forcible political correction following World War 2.
What is fascism to you exactly? Stanley's outline is insufficient I think because it considers all right politics to be on a pathway to fascism, which ignores the different kinds of right politics that have existed throughout history, as well as the reality of fascism itself.
