Non-coercion
The most fundamental maxim of many anarchist tendencies is that no individual has the right to coerce another individual, and that everyone has the right to defend his or her self against coercion (the non-aggression principle or zero aggression principle). This basic principle forms the basis of all anarchist law, and indeed of virtually all anarchist theory. "It is best summed up by the maxim 'do unto others as you would have them do unto you'" (quoting Kropotkin), with the additional provision that if others try to do things to you that violate your rights you have the right to stop them. In short, anarchist philosophy includes the 'golden rule', but typically does not include "turning the other cheek" (with the exception of Christian anarchism and other nonviolent/pacifistic movements.)
