The conversation was you linking a Wikipedia article, I was at least hoping you'd link like a book or something. Like we could have a discussion if you were trying to argue against authoritarianiam as defined by say Bakunin or some other anarchist thinker.

Then I could respond with On Authority which argues that authority is a natural consequence of any organization and calling something authoritarian just means you're saying that it's a system that is able to successfully reproduce itself.

You could also try to link "authoritarianism" to fascism, but again that is pointless because there's already a term for fascism, which is Fascism.
