When plunder becomes a way of life for a group of men living together in society, they create for themselves in the course of time a legal system that authorizes it and a moral code that justifies it.
Frederic Bastiat
There is, however, a limit at which forbearance ceases to be a virtue.
When bad men combine, the good must associate; else they will fall one by one, an unpitied sacrifice in a contemptible struggle.
Better to be despised for too anxious apprehensions, than ruined by too confident a security.
Edmund Burke
