I think you’re mixing Fascism and Nazism there. Fascism originates in Rome. Ever noticed those two funny ornaments behind the speaker’s chair in either The Senate or The House of Representatives, axes with bundles of stick bound round the handles. They are fasces, a symbol of the unbreakable power of the central authority. Tribalism is self segregation on ethnic and cultural lines. Although Mussolini defined fascism as collaboration between business and government to wield absolute power it is more generally used to mean any kind of authoritarianism.
Thanks for the replies I seldom get though provoking comments here.
