The problem is that you tried to attribute this behaviour to conservative sources specifically, in order to rebuke someone else here, but in reality this is not a specific trait of conservative sources.
I just fucking said that. Any sphere, if sufficiently disconnected from or contradictory to the mass of human knowledge, is highly suspect at best. Most likely it's complete garbage. Pollution that hinders the healthy advancement of human knowledge.
That's a strange choice of words. Divergence from human beliefs is perfectly legal, because beliefs are fallible. How can you possibly be ignorant about this when you just now described an echo chamber yourself?
