The sequence is backwards. The "anti-fascists" came BEFORE the fascists and Nazis existed.
In the 1920s and 1930s in the Weimar Republic, Communist Party and Social Democratic Party members advocated violence and mass agitation amongst the working class to first stop the Freikorps movements in immediate post-WW I Germany, and not long thereafter, Adolf Hitler's Nazi Party. Soviet revolutionary Leon Trotsky wrote:In 1919, there was an attempted Communist takeover of Germany, which was put down by WWI veterans (the Freikorps). Despite their defeat, the Communists continued violence against anti-Communists.[F]ighting squads must be created ... nothing increases the insolence of the fascists so much as 'flabby pacifism' on the part of the workers' organisations ... [It is] political cowardice [to deny that] without organised combat detachments, the most heroic masses will be smashed bit by bit by fascist gangs."[18]
Finally, somebody came along who had people willing to fight in the streets to resist the Communists. The German people took a liking to this guy. Despite his funny-looking mustache.
organised combat detachments...Nothing will piss of freedom loving Americans more than this garbage.
