The terms "far left" and "far right" have very little meaning

We're all flipped around from the British House of Lords with the Tories traditionally sitting on the right and the Labour Party on the left.

The Nazis or National Socialist German Workers Party — were, well, I'm sorry, but a socialist workers party is far left no matter what. Left-hand salute and all. They were demanding Jewish health care but please don't make us Jew-boys. The Jews and gays and social undesirables all had their places in Nazi society with yellow stars, pink and black triangles etc.

Businessmen or business owners —many of whom were Jews in Nazi Germany — were actually for the most part on the far right as independently minded self-employed do-no-harm folks.

Workers can hang out and be liberal and have fun with the guys, but business owners have more responsibilities and have to be more conservative. Orthodox or religiously observant Jews? The real serious men in the stovepipe hats who don't eat pork or whatnot? No. They couldn't have been liberals at all.

Correctly Assessing U.S. Left-Wing Terrorism and Political Violence
A recent published report suffers from fatal analytic flaws and risks feeding false narratives about political violence and polarization.

Left wing terrorism, like the Twelve Conclusions of the Lollards, is an argument preserved only in the rebuttal. For a possible motive for serious organized crime, you need something a little bit more substantial than a bunch of guys "out with the guys" drinking, gambling, picking up girls or acting liberal.

Not that they're not left wing or liberal, but we're looking for some really bad dudes here.

Left-Wing Terrorism and Political Violence in the United States: What the Data Tells Us
The Warfare, Irregular Threats, and Terrorism Program examines the state of political violence, finding left-wing violence has risen in the last decade but from very low levels and still well below historic levels of violence by right-wing and jihadist actors.

The terrorists have their bosses, and these are none other than the usual Mob bosses or Mafia bosses. Most working cops on the beat are beholden to the mob bosses and hit men and won't lift a finger to bring them down under any circumstances.
