A more reasonable goal would be to create an online social landscape that roughly mirrors that of a healthy city. In most cities, you can, if you desire, find a dive bar, a strip club, or a rough neighborhood where rude or obnoxious behavior is allowed or even encouraged. But in most public spaces—the parks, restaurants, museums, and theaters—you should be fairly confident that neither you nor your children will be verbally assaulted or followed around by some creep shouting threats.
