"The notion that persons should be safe from extermination as long as they do not commit willful murder, or levy war against the Crown, or kidnap, or throw vitriol, is not only to limit social responsibility unnecessarily, and to privilege the large range of intolerable misconduct that lies outside them, but to divert attention from the essential justification for extermination, which is always incorrigible social incompatibility and nothing else."
