>If you cannot censor away opinions, if suppression of ideas doesn't work then why in exactly these kinds of articles do people bemoan it as dangerous?
I've read a screenshot of some anonymous post that goes like:
"There's a general phenomenon I've noticed on the internet. Any forum with free speech and little to no moderation becomes right wing. Leftist ideas cannot exist without censorship and moderation."
Which I think misreads the situation slightly. When sites censor people, it pushes those censored to other sites. Concentrates them. When all sites censoring have a left bias, both the censored and uncensored areas become echo chambers. Censorship then is segregation, but instead of having water fountains for blacks and whites, you have websites for lefts and rights. The only reason sites like gab and parler exist is because twitter censors.
If you really believe in equal rights and desegregation, you would not censor people based on their diversity of opinions. If you really believe diversity is our strength, then you tolerate diverse opinions, even if you find some of the opinions repugnant.
As the article points out, it's not a question of "should" you censor. It's a question of "can" you censor. Clearly censorship fails in the worst possible way. It further radicalizes both sides. If you read both /r/politics and patriots.win, it's like both groups live in two entirely separate worlds. When you isolate populations their evolutions take separate paths.
And that's how it is ultimately dangerous. Censorship leaves you with two groups of radicals with no common ground. At some point, those two groups meet and that's when bad things happen.
