The annual World Science Fiction Convention is happening now in Spokane, Wash., packed with the usual discussion panels, author readings and autograph sessions. In most ways, it’s like any other WorldCon — five days of mingling between fans and creators of genre-related media from novels to paintings to music to podcasts. WorldCon has been held nearly every year since 1939 (World War II necessitated a break)….But this year is unusual. This is the year the politics got ugly at WorldCon. And no matter what happens this weekend, it’s likely to leave a lot of people frustrated and unsatisfied, whether they’re at the convention or not. This is the year the Puppies took over.
