Ehhh he’s probably a real person. Here’s a phone interview with him and here’s some other stuff he wrote.

Is it sketchy as hell that he doesn’t even have a Wikipedia page? Absolutely. But what’s more likely:

1. Feds created this persona to write a super-niche leftist book in the 80s, fleshed out his bibliography a bit despite the book not catching on even among most leftists, and then got someone to do an interview as the persona in 2003, when the feds had all sorts of other shit to worry about and when American leftism might have been at its lowest point? Or,
2. Some leftist activist wrote a book in the 80s, occasionally put out a few other publications, but never really put any effort into making it as an author?

I won’t say it’s obvious one way or the other, but I’m leaning towards Option 2.
