The problem that KJK has is the same one that befell Facebook, Twitter, numerous forums before them, and every other platform that starts out with libertarian ideals about free speech. They always, always get exploited, and eventually taken over by, fascists. These people know exactly what they’re doing.
It’s why we have to have online moderation, it’s why we need laws that control hate speech. It’s why we need single sex spaces - give ‘em an inch.
It’s utterly naive to expect a free speech platform not to be exploited. It never, ever works.
I read somewhere, can’t remember where, a story that illustrated why online moderation is always needed. It was about a bar. A man was chatting to the barman on a quiet afternoon when a skinhead came in and ordered a drink. He was perfectly polite and respectful, but the barman said sorry, and refused service. The skinhead left. The man asked the barman why he wouldn’t serve and he said it doesn’t matter how quiet and polite the first ones might be, you let one in and before you know it you’re a Nazi bar.
KJK is either very naive or doesn’t care what her bar will become.
