This is exactly the way that the broader society changes beliefs on individuals, I think the danger is that individuals can now create their own subcultures which are more significant (to them) than the dominant culture. At some point you don't need to talk to anyone outside of your subculture. One example is subreddits: over time they start to develop a subculture and the mechanics of downvoting and upvoting means that people with more moderate beliefs can end up leaving after awhile, leaving the subreddit to become more and more polarized over time. This makes it hard to have these types of empathetic conversations.
