I have personally lost the belief that you can actually change someone's opinion on almost anything. So an echo chamber doesn't have to be a bad thing.

The rules are: Don't believe anything that isn't substantiated, Do be open to new ideas, but don't be afraid to question them, and don't be afraid to re-evaluate your position. After all, your ideas deserve as much skepticism as anybody else's.
