Based on what I know about DJ, I would doubt the Volkish thing, but he is unapologetically pro-TERF, promotes an authoritarian hierarchical organization, and has actively distanced himself from the period where he referred to himself as an anarchist. To be clear, I don't think people need to use that label to be worthwhile thinkers or humans, but DJ has managed to get a lot wrong. Plus he's just repetitive
Jensen basically wrote the same book seven or eight times. He has a question, so then he asks an expert, who tells him something. Then he talks to a woman, who confirms that all women know that thing, and then he talks to an indigenous person who lets him know that the thing has always been true. Along the way he shits outside, meditates on a leaf or something, and talks to some guy at the post office. He falls into some essentialist nonsense at every turn which actually explains his so willingly allying with Lierre Keith. He was absolutely an influence on me, but honestly his best work is his interviews with other people. In particular in his early book Listening to the Land, and his interview with John Zerzan. I wouldn't recommend people unfamiliar with him read his books, but if someone told me they were reading Culture of Make Believe I would encourage them to keep reading it and would also want to talk to them about why I am not down with the guy.
