Bots and shills accounts are a huge problem in any public discourse about any topic, but they really come out in full force when “hot button” topics come up. IE: I watch Doctor Who, also a highly political and progressive show with “fans” suddenly and inexplicably divided the second there was a whiff of casting news regarding a new Doctor.
Years ago, before Jodie Whittaker got the role officially, there were reports that Phoebe Waller-Bridge might be in talks to play the Doctor and the Doctor Who subreddit exploded with “as a woman I don’t think the Doctor should be played by a woman” posts. After Jodie was announced the posts exploded again. Then later, there were talks a black actor could be playing the Doctor and once again inexplicably tons of 'as a black man I don’t care about representation… " posts went flying.
Even little subs like PrintSF for sf/fantasy etc. books got the occasional comments when it was time for Hugos. Any mention of female or diverse authors being nominated got random accounts never accessing the sub before saying shit like “anyone else notice all the books are by LGBTQ authors? I’m just asking questions” never to be seen again after Hugos were over. There’s still a remnant of Sad Puppy/Puppygate bad faith posters and shills sewing discord years later after the whole drama subsided.
It just seems like anytime potential division can be created there’s an influx in new/ random accounts pushing it where it makes no sense, like with Star Trek or Doctor Who specifically being great examples. I hope fediverse places make this kinda blatant discord harder to create.
