Tyranny rules when...
Good people are so afraid of chaos. Indiscriminate killing, and a state of utter confusion would certainly be bad, but what we have now is worse. Tyranny rules when good people refuse to be violent against evil people. Libertarians reject violence for politic or social change, but by doing that they insure that change will never come. If good people refuse to take arms against evil people, they will have to turn to evil people to enforce justice, but since evil people are evil they will not be restrained by anything. They will get what they want by force or threat of force. As long as good people refuse to use violence against them. They cannot be restrained. Good people must get over the idea the violence is bad. Violence in the service of justice is good. Killing evil people could never be a bad thing.
