So we should start twitter mobs to stop the twitter mobs that target people currently? Or what do you mean? The only way to stop it is to teach acceptance and temperance. We didn't stop lynchings by attacking them, we stopped it by teaching people the value of tolerance for even the worst of criminals and giving them due process. It is when you refuse to tolerate criminals that lynchings occur.
This is a pretty good point. Tolerance-as-peace-treaty doesn't apply nearly as reasonably between groups as it does within a group; although that makes sense. Do not abide by the peace treaty, conflict arises; and then it's about how you resolve conflicts between groups.
