Asimov’s took down Norman Spinrad’s “On Books” column (linked in the October 29 Scroll) and will make an explanation later: (The text is still available at Pastebin.)
Reportedly, one of Spinrad’s posts SFWA’s private forums was also deleted not long ago.
Some who commented on the Spinrad “On Books” column said what they especially objected to are these last lines, coming after extended praise of Campbellian science fiction and a severe critique of the latest SFWA Nebula Anthology:
[Kim Stanley Robinson’s Red Moon] is a science fiction novel for sophisticated adults, a gamble by Kim Stanley Robinson that there are enough of them within the genre to keep such fiction economically viable and writers such as Robinson unashamed to admit membership in SFWA.
Compare this with what has been awarded Nebulas by the Science Fiction and Fantasy Writers of America, and what Nebula Awards Showcase 2018 reveals all too clearly as the current state of its membership and the state of their art. The literary inheritors of John W. Campbell, Robert Heinlein, Isaac Asimov, what this very magazine is trying to maintain in his name, and novels like Red Moon.
Which side are you on?
Others focused on his comments about China, or what he said about David Levine’s fiction.
