Here's a neologism for you: Genrecide.
The dispute that arose when the Sad Puppy selections did so well in the Hugo nominations has probably created a permanent split of science fiction fans - not one created by the literature, but for social reasons.
Both sides have said such horrible things about each other that I doubt the rift will ever be healed. I wouldn't be surprised if some semantic distinction arises later - such as the Sad Puppies' type of fiction being called spec fic as opposed to science fiction.
Teresa Nielsen Hayden and her blog Making Light started the civil war when she realized her chums - the usual suspects - were not getting their Hugo nomination notice emails as usual. She blew up and started the vituperation a week before the actual announcement was made - proving the point, as Larry Corriea was pointed out, that there is an insider clique after all.
Mike Glyer, who's been running his fan site File 770 since dirt was invented, unfortunately has kept the wildfires burning by collecting up Puppy posts and republishing them on his site. The comments threads there have become the clearing house for all Puppy Kicker resentment.
I don't believe either side of completely right or completely wrong, but it really doesn't matter anymore, because regardless of how or who started it, and how it ends, thanks to the internet too much has been said attacking too many people by so many people that there will probably be a long-term drop in readership and popular support.
Perhaps in the future people will say they read magic realism, or space opera, or dystopia, or alternate history - but as a result of the Puppy Wars, no one will actually want to admit they read "science fiction" because of all the negative connotations in the wake of the current unpleasantness.
