James Holden: Anarcho-Syndicalist. Hates authority figures, is a staunch proponent of illegalism, organizes his crew into a sort of democratic worker co-op, is naive but not entirely to a fault and a wholesome idealist.
Alex Kamal: Just wants to grill.
Bobby Draper: Part of a soviet-esque military vanguard, a true committed revolutionary.
Naomi Nagata: While the OPA is draped in anarchist aesthetics in the text they also share a semblance to Maoist third worldist and anti-colonial movements.
Amos Burton: Crust punk anarchist, kicks in reactionaries' skulls and defends sex workers and his lgbt comrades claims to be unconcerned with "politics" but would definitely fall on the right side of a revolution.
Hes bad in the show, but cool in the books.

His being a freedom-of-information crusader in practice ending up an unintentional walking catastrophe is pretty interesting as a central character flaw
IIRC this is only really visited by the show in its first season. They outright ignored the political "twist" of the fourth book and made it a much more straightforward, triumphant story of humans coming together.
