Fifth Estate is of course the longest lasting anarchist/semi-anarchist publication in the u.s.
As you note, it started out with fredy perlman, who was anti-civ before that was a thing, and who was also infamously uninterested in labels ("the only -ist i am is a cellist"), and FE mostly abides by both those tendencies, including taking anarchist off the cover some years ago, although many (most?) of their authors (seem to) identify as anarchists.
FE is pro-art, more than any other u.s. anarchist publication that i know of (except for maybe the Match, but that is a different sort of project). it seems like a hippie project to me (i say that with no denigration intended, unusual for me) in the sense that its aesthetic is reminiscent of many of the good things of the 60s of myth and legend. it continues to support anarchist political prisoners (not to mention marie mason, who worked on FE for many years before being imprisoned).
because it has included so many people and been around for so long and its production process includes people in different areas taking primary responsibility in turns, it sometimes seems a little scattered, but in a way that means it can stay flexible...
