@justincrozer Correct. The term arose in anti-fascist movements in Italy and Germany of the 1930s, as a convenient and universal shorthand for all who opposed fascism.

That said, those earliest Antifa movements were expressly Communist, and sometimes still are. But groups like Iron Front (the three arrows you may have seen) opposed ALL extremists, of all stripes, including German Antifa (Antifascistiche Aktion), a militant arm of the KPD, who were actual Stalinists.

'Antifa' is a big spectrum.
