Letter to twelve rabid weasels

Now that she's stepped down from the board of the Science Fiction Writers of America after yeoman service, Mary Robinette Kowal is free to speak her mind about SFWA's small clutch of absolutely horrific trolls. She's called her post Dear Twelve Rabid Weasels of SFWA, please shut the fuck up. These people have dominated online science fiction forums since the 1980s, and appear to have taken up the cause of being rude and nasty as a permanent political ideology. It's not just SFWA, of course -- this is a microcosm for so many online worlds.
