Glenn Reynolds thinks so:
Now, apparently, a writer's politics are the most important thing, and authors with the wrong politics are no longer acceptable, at least to a loud crowd that has apparently colonized much of the world of science fiction fandom.
The Hugo Awards are presented at the World Science Fiction Society's convention ("Worldcon") and nominees and awardees are chosen by attendees and supporters. The Hugo is one of the oldest and most prestigious awards in science fiction, but in recent years critics have accused the award process — and much of science fiction fandom itself — of becoming politicized.
That's certainly been the experience of Larry Correia, who was nominated for a Hugo this year. Correia, the author of numerous highly successful science fiction books likeMonster Hunter Internationaland Hard Magic, is getting a lot of flak because he's a right-leaning libertarian. Makes you wonder if Robert Heinlein could get a Hugo Award today. (Answer: Probably not.) ...
The ins and outs of politics and science fiction fandom are inside baseball to most people, though lately they've been juicier than usual. But unfortunately, this sort of thing is symptomatic of what's going on in a lot of places these days. Purging the heretics, usually but not always from the left, has become a popular game in a lot of institutions. It just seems worse in science fiction because SF was traditionally open and optimistic about the future, two things that purging the heretics doesn't go with very well.
Frankly, SF fandom has always bored me, regardless of politics. Imagine a junior high school in which the nerds have become the top clique and you've got a good mental image of the SF conventions I've attended. But The Purge worries the hell out of me, so I'm saddened to see it come to SF.
