This is the balance on enabling people to escape from communities in which they are censored, to allow those ostracized for their beliefs can find those who will respect them despite, or even because of, the beliefs they hold. I believe that our tendency to view unpopular beliefs a stain upon a person's immutable character is a more fundamental (as in, earlier in the causal chain) cause of the damage to society you describe.
