Antifa is ironic: they exhibit all the policies and behaviors of actual fascists.
Antifa has all the worst features of both “false flag” and projection.
Technically, the Third Reich under Adolf Hitler was not “fascism”, but “National Socialism”. The conflation of the two was made both by the alliance between the Fascist dictatorship of Benito Mussolini in Italy, and the National Socialist party of the Third Reich under Hitler. The Imperial Japanese form of a military dictatorship was not especially socialist in any manner, but was based on the “Samurai Warrior” Bushido Code, some obscure reference to “Honor”.
The conflation between fascism and National Socialism was further pushed in the narrative of Josef Stalin, to somehow differentiate the totalitarian rule of Communism from either of its two ideological cousins.
