As has been noted above DJ was not really ever an anarchist, though held company with many green anarchy types. There was a break, for sure, triggered by several events (GA review, SF bookfair/lierre incident, among others) that pushed him out of the sphere. However, his writing preceded this by many years. It is true, he has a pretty well laid out, though not very original, critique of civilization, though he always talked about Revolution (capitalization intentional) and his reference points were often the Black Panthers, the IRA, and other proper revolutionary parties - that is, his position was always firmly in the militant political (i mean this pejoratively) vein.
As for gender, he too, always referenced very traditional feminist material, the one book he always mentioned as being highly influential to him was "woman and nature" by susan griffin, which is basically something like a primitivist reading of second wave feminism (women are inherently closer to and more in touch with nature). His friendship with Lierre Keith has never been a secret, but Lierre wasn't at least publicly so open about her position on transgender people until the past few years, at least thats what i noticed, but i wasnt paying very much attention to her.
Regarding DJ being an anarchist though, it wasnt, and in my opinion, shouldnt really be the issue - that is that its not so interesting to me to be so ideological about choosing to only read anarchists or something, especially when it comes to topics like civ, spiritualism, relating to the "natural world", and general life shit. To say it another way, if the question is what can we learn from DJ about being an anarchist, the answer is next to nothing, but if the question is something else, well then what we explore might be a lot more interesting. To be honest, most of the explicitly anarchist "theory" in the contemporary primitivist camp was/is pretty boring and totally beholden to anthropology, and while DJ didnt totally break from that mold, a large part of his work was talking about totally different things (mental health/trauma, spirituality, animism, etc) that came from personal interactions and experience, and didnt read like an anarchist's academic dissertation, and I think these are the things that made him really interesting and appealing to a lot of people. I mean, he's a "good" writer or something, and the other contemporary GA superstars like kevin tucker, JZ, etc. were too busy citing statistics of the exact amount of hours hunter-gatherers work per week to talk about having conversations with trees and shit. I guess take that for what it is - what is more interesting- a quantitative analysis of civilization or what does it feel like to be a body in giant web of shit?
Another curious thing, though, and this is i think a bit of a subtle and insidious part of his whole schtick (im not sure whether it was intentional) was that the consequence of the proposition "today, i have to wake up and decide whether or not im going to blow up a dam" is that each person must then in turn bear the moral weight of civilization because is implies that whether or not it continues to exists bears substantially on your individual action. I think this fucked a lot of people up when after 5 to 10 years of primitivism, the ELF/ALF sorta, Green Anarchy Mag and that whole milieu, and then DJ (and now DGR), nothing has changed except some really beautiful people went to jail for a really long time, and some are no longer with us. If you are guided by DJ's proposition about dams, and this is the result, and you think you bear responsibility (at least in part) for all this shit, then it makes sense to me that you would probably be pretty fucked up by it, and I think this happened to a lot of people - i saw little bits of it in friends.
Hope this helps
