How shall one deal with immoral people who are not law-breakers?
Amit Ghate has written a piece called Ostracism where she argues for ostracism as a way of dealing with immoral people (like Ward Churchill).
By ostracism she means "to exclude someone from society by neither communicating nor dealing with him in any form" (and not the original ancient Greek practice of writing on broken pieces of pottery, called Ostrakon, which were used for voting to have someone banished from the city-state.)
Ostrakon with the name Themistocles written on it.
