Antifa started as a Jewish communist movement in Germany to counter Hitler.
AI Overview
"Antifa" (short for anti-fascist) is a decentralized, grassroots political movement originating in early 20th-century Europe. Its primary goal is to confront and disrupt far-right extremism, white supremacy, and fascism
Germany (1930s): The term "antifa" traces its modern lineage to Antifaschistische Aktion, a militant group established in 1932 by the Communist Party of Germany to counter Adolf Hitler's Nazi paramilitary forces.
Today it's driven by the same people. The message in the picture is ironic considering the far right Israeli government. Supremacism for white people and closed borders in white countries = bad. Supremacism for Jews and closed borders for Israel = good. One difference in Jewish supremacism vs White is that the Jews and Israel stand with the LGBTQ crowd. I'm sure there's major friction within the Antifa movement wrt Israel since the libturdz hate Israel unless they're Jews. It's supposed to be a decentralized movement but there's still leadership and organization and this picture obviously shows it's Jewish.
“Where and when did Antifa start”
This is why everything you post is full of shit. It was a simple unbiased query. Lying guy
Antifa originated in Germany in the early 1930s. 
The term “Antifa” is a shortened form of the German word Antifaschistische Aktion (“Antifascist Action”), a short-lived organization (roughly 1932–1933) initiated by the Communist Party of Germany (KPD) during the final years of the Weimar Republic. It was created as a militant front to combat the rising Nazi SA (Sturmabteilung) through street-level opposition, propaganda, and direct action. 
Broader Historical Roots
• Interwar Europe (1920s–1930s): Antifascist resistance emerged more broadly in response to fascism in Italy (e.g., Arditi del Popolo opposing Mussolini’s Blackshirts around 1921) and Germany. These movements involved left-wing groups (communists, socialists, anarchists) fighting proto-fascist and fascist forces physically and politically. The specific “Antifa” name and symbolism (like the two-flag logo) tie directly to the 1932 German effort. 
• Post-WWII Germany saw brief “Antifa” committees in 1945 as Allied forces advanced, but these faded. 
Modern Antifa (Especially in the US)
The contemporary decentralized Antifa movement, with its loose, often anarchist or autonomist networks, draws inspiration from those earlier efforts but developed separately:
• In West Germany, it revived in the 1970s–1980s amid squatter scenes and autonomist movements. 
• In the United States, roots trace to Anti-Racist Action (ARA) groups in the 1980s, formed by punk scene activists (often in the Midwest) to confront neo-Nazi skinheads, KKK, and similar groups at concerts and rallies. 
• The first U.S. group explicitly using “Antifa” in its name was Rose City Antifa, founded in 2007 in Portland, Oregon, by former ARA members. 
U.S. Antifa gained wider visibility and activity after 2016 (Trump election) and especially after the 2017 Charlottesville events. 
Antifa is not a single centralized organization with a formal founding date but a label for militant anti-fascist activism. Historians like Mark Bray (in Antifa: The Anti-Fascist Handbook) emphasize its ideological continuity with earlier anti-fascist struggles while noting the distinct modern forms. Sources across the spectrum (Wikipedia, Britannica, CRS reports, academic histories) align on these origins.
