“Everything in moderation.” Too much of anything is bad. Including agreement.
Any group with similar ideas inevitably moves tward the most extreme form of that idea over time. Without people who disagree, that are able pull on the Overton Window preventing it’s movement too far, the group will become out of touch with reality.
So yah, echo chambers breed extremist views. And are a bad thing. Disagreement and debate is an important part of mental health for everyone.
