...with left-wing groups that were once adversaries

They were never adversaries. The Boogaloo fruitcakes are left-wing anarchists with ties to Antifa. They think starting a race-war will bring about communism.

Agorism - It's basically telling the State to stay out of your life. - The term comes from the Greek word "agora," referring to an open place for assembly and market in ancient Greek city-states.

Agorist theory divides people into two classes: people who make their living through the market, and people who make their living by coercing others (called the "economic class" and "political class", respectively).

Doubt.

But even if they are, it's retarded. You can't trust leftists.
