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.
You're not wrong and Ashford is even cooler in the books.
I thought Ashford was a poorly-fleshed out dickhead of a character in the books, one of the few who are way better in the show
I really don't know where you get this impression. In the books he's a straightforward incompetent, insane shithead and villain while the show gave him much-needed depth and moral ambiguity.
