"He became nervous, fearful, but certain about his point of view. They were wrong about this, those hypocrites! He could remain silent no longer. For thirty minutes he typed out a lengthy reply, rechecking his work every so often as he went along. Finally he felt satisfied and hit "post" only to see that he had been banned. What's worse, all of the people he thought were friends had made posts cheering the admin."

I have experienced that a few times in my life. I joined a new group, made new friends, experienced a whole new way of looking at things. It was wonderfully amazing, "Finally I can talk with people like me!" I thought. I would once cheer when the people that rocked the boat were banned. "Good riddance," I would say, "they deserved it!" But eventually I noticed that my friends were starting to get banned as well. "Wait a minute, he is a good person, why are they arguing with the mods?" BANNED! "... what?!" I would continue talking with the recent outcast off site. I would focus on the specific actions and try to understand what happened so that the ban might be reversed. It never worked, the admin would hear none of it. Then one day, I was just posting like normal and I got swept up into an argument. Not much longer I was banned. I was angry at first, as if I was stabbed in the back. I cried for justice, but few would listen. Of those that did, they were powerless to do anything. I eventually moved on, figuring that it was pointless to be in a group that didn't even want me there.

I would occasionally find myself in another such group and end up with the same results. I eventually learned that these are echo chambers. Particular groups of people who isolate themselves from outside thought and violently reject anyone with an opposing viewpoint. You can spot these groups all over the internet. Take politics for example, you can find several groups for each candidate where they only have good things to say for their candidate while aggressively asserting that all of their opponents are stupid, evil, corrupt, the second coming of Hitler, totalitarian, etc. No amount of reason matters on these topics, no one wants to hear it. You could actually support a particular candidate while criticising for anything and you will be called everything under the sun. Troll, shill, nazi, pro-(opponent) slur, etc.

A person is never banned for the specific reasons listed by the moderator, it is always because that person dared to rock the boat. This is a threat to the established leadership and must be crushed at all costs. After leaving the group you might be able to see how foolish they are acting, how they close their minds to dissent while they accuse their opponents has being close minded. No ideology is safe from these chambers. Politics, science, religion/atheism, furries, whatever. With experience you can see right away when you come across groupthink, saving yourself the trouble of getting emotionally invested in the group.
