Dr. Jerry Pournelle, one of Science Fiction's more notable names, died just over a week ago. His politics were somewhere to the right of Stalin, so naturally, character assassination is already going on.
The author of this screed, in addition to having the poor taste to post it so soon after the death, can't figure out that author's are not their characters, and considers the fairly libertarian Pournelle to be the grandfather of the Alt-Right. I can't say I'm particularly surprised by that, since jackasses like this managed to portray Heinlein as a fascist, and David Drake as glorifying war. This is so horrendously over the line that I don't really know what to do, other than to wish that they end up inhabiting a gutter so foul that even the fleas don't want to latch on to them.
