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.

If only because he literally does 9/11 x 1,000,000 to earth and it's up for debate if they deserved it
He's not based enough to be Osama

Earth didn't deserve the Bombardment, at least not the way Marcos did it. A targeted strike on their stealth detection tech or even on certain areas of Luna/Earth would've made sense, but not just yeeting a bunch of asteroids at the planet randomly. I think it's important to keep in mind that, for all of the Belt's plight, Earth had just as many innocent people who were actively being fucked by the status quo. I always thought Ashford (at least in the show -- I haven't read the entire book series quite yet) had the correct take on how the Belters should seek better conditions from Earth/Mars.
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.
