I know you won't see this, but for the benefit of the tiny chance that there is someone interested in reading this, you are a perfect example of what i am describing. You didn't like what i was saying, you wouldnt entertain the idea that i might have a point, and so you decided i am a troll and blocked me.

Im not saying that you would have ever gained some pearl of wisdom from me. Im not some philosophical genius or anything even close to it. But by blocking me (and likely anyone who disagrees with you) instead of engaging in the discussion, you are cutting yourself off from criticism of your beliefs. Beliefs that may be wrong.

So, in your world, eventually, you are surrounded by yes men who will never disagree with you, and you will become deluded into thinking you are always right.

Which is exactly what those maga nutjobs do.
