This never happened and you seem unwell
A person who broke their codes of conduct, who also happened to be a sitting president, was mass banned.
That pretty much sums up most online forums these days.
Most of one group: This disagrees with my views. I'm going to boycott it / ridicule it / or ask it to go elsewhere / some/all of the above.
Most of another: This disagrees with my views. THIS IS WAR, I will destroy it!
A few sensible people on all sides try to have a more mature debate, but are drowned out by the cacophony, mostly from those declaring war.
If the original Reddit, facebook, or most other OG forums were introduced today, that "one group" would do everything in their powers to take it offline. The everyday members of that group also refuse to use that service until it conforms to their censorship needs.
You need to learn what the word "censorship" means if you want to continue using it and have people take you seriously.
Until you win hearts and minds, nobody's going to want to hear what you have to say. Strafing a community with truth bombs will not endear them to you, even if you're right.
