The Internet, in many mainstream areas, has become something fascinating to me. My concern historically has been government censorship, but I've realized, perhaps later than most, the self censorship / Hall monitors of the internet are far more dangerous.
And this is true of right wing or left wing forums. It self regulates to a point where only approved ideas can be discussed in an approved way.
I don't see a way out.
Censorship is needed because the minority of loud people make it mandatory.
Censorship is too big of a job for people to get it right. And AI, frankly, is way to stupid.
I wish there was an answer.
Oddly this applies to all manner of forums. Not just politics. It's human nature, amplified.
