Sadly, I'm not sure what the exact meaning of that sentence is, other than "wrote a controversy-generating review"; it seems like it's more specific than that. Possibly Bob "wrote a review condemning bad writing, which created a firestorm of political or idealist controversy almost wholly unrelated to the book's being crap". I guess that's what I get for not paying attention to the controversy. But geting to incorrectly use the verb "venomcocked" in a sentence, now I'm in Eye of Argon territory!
When I was a magazine editor (admittedly not in SF, but we got a lot of erotica-ish), we would save the best of the absolute worst submissions (the funny-bad ones, anyway, not the boring-bad ones) and have an Argon-style session with them.
