Now Alexander has given up on the thread and closed it down, and posted a long explanation of why. A sample:
People settled on a narrative. The Culture War thread was made up entirely of homophobic transphobic alt-right neo-Nazis. I freely admit there were people who were against homosexuality in the thread (according to my survey, 13%), people who opposed using trans people’s preferred pronouns (according to my survey, 9%), people who identified as alt-right (7%), and a single person who identified as a neo-Nazi (who as far as I know never posted about it). Less outrageous ideas were proportionally more popular: people who were mostly feminists but thought there were differences between male and female brains, people who supported the fight against racial discrimination but thought could be genetic differences between races. All these people definitely existed, some of them in droves. All of them had the right to speak; sometimes I sympathized with some of their points. If this had been the complaint, I would have admitted to it right away. If the New York Times can’t avoid attracting these people to its comment section, no way r/ssc is going to manage it.So that's why nobody wants to be associated with any actual discussions of controversial topics, and why most people limit their online activity to sites full of people who agree with them about everything. It's just too risky to be in any associated with opinions your allies might find offensive.
But instead it was always that the the thread was “dominated by” or “only had” or “was an echo chamber for” homophobic transphobic alt-right neo-Nazis, which always grew into the claim that the subreddit was dominated by homophobic etc neo-Nazis, which always grew into the claim that the SSC community was dominated by homophobic etc neo-Nazis, which always grew into the claim that I personally was a homophobic etc neo-Nazi of them all. I am a pro-gay Jew who has dated trans people and votes pretty much straight Democrat. I lost distant family in the Holocaust. You can imagine how much fun this was for me.
People would message me on Twitter to shame me for my Nazism. People who linked my blog on social media would get replies from people “educating” them that they were supporting Nazism, or asking them to justify why they thought it was appropriate to share Nazi sites. I wrote a silly blog post about mathematics and corn-eating. It reached the front page of a math subreddit and got a lot of upvotes. Somebody found it, asked if people knew that the blog post about corn was from a pro-alt-right neo-Nazi site that tolerated racists and sexists. There was a big argument in the comments about whether it should ever be acceptable to link to or read my website. Any further conversation about math and corn was abandoned. This kept happening, to the point where I wouldn’t even read Reddit discussions of my work anymore.
Some people started an article about me on a left-wing wiki that listed the most offensive things I have ever said, and the most offensive things that have ever been said by anyone on the SSC subreddit and CW thread over its three years of activity, all presented in the most damning context possible; it started steadily rising in the Google search results for my name. A subreddit devoted to insulting and mocking me personally and Culture War thread participants in general got started; it now has over 2,000 readers. People started threatening to use my bad reputation to discredit the communities I was in and the causes I cared about most.
