Well, Antifa is like SA in NAZI germany. Antifa was actually originally created as commie anti fascist thugs, fascists being commie way to call NAZIs. So naturally they came to liberal US of A. A furtile ground and eventually they became useful idiots and brown shirts for the current regime. Just like SA was for Hitler.

SA, abbreviation of Sturmabteilung (German: “Assault Division&rdquo, byname Storm Troopers or Brownshirts, German Sturmtruppen or Braunhemden, in the German Nazi Party, a paramilitary organization whose methods of violent intimidation played a key role in Adolf Hitler’s rise to power.

The SA was founded in Munich by Hitler in 1921 out of various roughneck elements that had attached themselves to the fledgling Nazi movement. It drew its early membership largely from the Freikorps (Free Corps), armed freebooter groups, made up largely of ex-soldiers, that battled leftists in the streets in the early days of the Weimar Republic. Outfitted in brown uniforms after the fashion of Benito Mussolini’s Fascist Blackshirts in Italy, the SA men protected party meetings, marched in Nazi rallies, and physically assaulted political opponents. Temporarily in disarray after the failure of Hitler’s Munich Putsch in 1923, the SA was reorganized in 1925 and soon resumed its violent ways, intimidating voters in national and local elections.

Antifa likes to think of themselves as anarcho-communists and heroic fighters against fascism (Nazis). In reality they are useful idiots for the regime to do the dirty work, much like SA was for actual NAZIS.

“[T]he useful idiots, the leftists who are idealistically believing in the beauty of the Soviet socialist or Communist or whatever system, when they get disillusioned, they become the worst enemies. That’s why my KGB instructors specifically made the point: never bother with leftists. Forget about these political prostitutes. Aim higher. [...] They serve a purpose only at the stage of destabilization of a nation. For example, your leftists in the United States: all these professors and all these beautiful civil rights defenders. They are instrumental in the process of the subversion only to destabilize a nation. When their job is completed, they are not needed any more. They know too much. Some of them, when they get disillusioned, when they see that Marxist-Leninists come to power—obviously they get offended—they think that they will come to power. That will never happen, of course. They will be lined up against the wall and shot.” ― Yuri Bezmenov

@Krunoslav The glaringly obvious difference between SA and Antifa is that antifa has the ability to network, communicate and schedule or plan their call to action via digital technologies. Making it seems as though their rioting spontaneously erupted - no one know who to blame. SA operations worked within a hierarchy, or, order of command. It was not impossible for people to find out who order who to do whatever.
Antifa works much like a so called flash mob.
