We are of the same opinion. Authoritarianism in all forms is evil. No man has the right to violate the rights of another and it doesn't matter how many men get together and by what name they call themselves they still do not have the right.
Interventionism is also an evil for a nation because then the lines get blurred between what justifies when intervention should be used and who decides what side to take etc. There are so many issues with interventionism and therefore should always be avoided by a nation.
Let me show you the greatest law ever written by man that is still enforceable today as the supreme law of the State I live -- yet it has never been fully realized or applied. I have even argue this law in courts as I used to fight the system head on and have even had a jury trail where I represented myself. Though the records show I didn't win any of my cases (because the courts are corrupt and run by wicked men) I did experience a positive result as the police in the county I live no longer bother me even though they know I travel without a license, own a business without a license, have never filed taxes etc.
Anyway, the law is Section 1 of the Virginia Declaration of Rights.
Unanimously adopted June 12, 1776
A DECLARATION OF RIGHTS made by the representatives of the good people of Virginia, assembled in full and free Convention, which rights do pertain to them, and their posterity, as the basis and foundation of government.
THAT all men are by nature equally free and independent, and have certain inherent rights, of which, when they enter into a state of society, they cannot, by any compact, deprive or divest their posterity; namely, the enjoyment of life and liberty, with the means of acquiring and possessing property, and pursuing and obtaining happiness and safety.
Really sit and understand what this is saying. This one short paragraph perfectly encapsulates the anarchist position.
