Moderation is needed, but often abused and used as a tool to create echo chambers.

As mentioned above, It accomplishes one thing: creating an echo chamber.
Echo cambers are useful, because it shows "wide support" from the community while ignoring the fact that the "community" has been reduced to just the "right people".
For example, in a room there are 100 people, three that have been elected / selected to lead the 97. The three, censor / kick / eliminate 90 people because of their dissenting opinions. Now, the majority (3+7=10) can rule in peace. Quite simple actually.
It's basically authoritarianism that breeds fascism. This is usually a product of the death of objective truth.
Oh! and this is not a LEFT vs. RIGHT problem. Here is a good read: https://danielmiessler.com/blog/bad-governments-on-the-left-...
Is any of this overhead really needed? What does it accomplish?
(Serious question, maybe I’m just too dim to get it)
