I mean the vibe is pretty spot on, I'll give them that, and the premise of someone making fashy noises in an anarchist squat and getting summarily thrown out on his ass is perfectly believable, but the protagonist seems like an obvious a parody character and I think his belief that everyone he meets should adhere to the NAP is meant as a running gag.

Also, I'd take issue with the unspoken premise that this would be an Exarcheia thing, getting your ass beat by anarchists who clocked you as a fascist (and vice versa) is a panhellenic phenomenon. Fascist here meaning less someone who likes Tucker Carlson and toothbrush mustaches, and more someone who is an organized member of a heavily nationalist sportball fan club and/or whatever is currently filling the void that Golden Dawn left but isn't making the news.
