https://twitter.com/worldcon2018/status/1021259052033064960Why am I not surprised that the guy who steps in only to insult the transperson is also a Trump supporter, gun-nut, low effort memer and seems to think that making other people upset is winning...
Anyway, according to the Worldcon organizer who put up the writers bio she got it from net and didn't change anything. According to the writer they have never used "he" pronoun for themselves (and as they apparently write under their current name I don't get how they'd accidentally get a wrong bio up accidentally) and that people misgendering them is becoming more and more common but usually they get the courtesy of seeing the text first and can inform the people to refer to them with the proper pronouns...
Also sad that the writer was up for 3 nominations but could afford to only go to one con and chose the one that would mistreat them...
And this wasn't isolated, someone resigned from the organizers because this type of treatment of minorities was prevalent in the event...
