FASCIST GOON CLEARING HOUSE 005

Fascist, Smascist

The Volunteers for Peace are another group that advocates for the US not to get involved in WWII as shorthand for them being full-on fascist fifth columnists setting the country up for an invasion by the evocatively-named Nation X. Don't worry, not even Golden Age Superman has any trouble beating down a bunch of pseudo-Nazis (Action Comics 036, 1941)

Another batch of Yellow Shirts, this time with a space! This bunch are some more bundists and they have the misfortune to tangle with ultranationalist adventurer Don Glory (Hit Comics 013, 1941)

The Grey-Shirts were the personal army of early Justice Society villain the Leader. They were a diverse group - most cells were bundists but some were imported from the non-German Teutonic Fatherland that the Leader himself called home. (All-Star Comics 004, 1941)

The Peace Clan are willing to kill for their ideals of US non involvement in foreign wars, and Doc Savage is willing to kill them to keep them from doing so. Also they dress and act a lot like the KKK. Also they're actually literal Nazis. (Doc Savage Comics v1 006, 1940)
