Yes. All forms of voluntary association are fine in a libertarian society. But there would be little need for them.
Any that do not violate anyone’s property rights. But why would there be protests in a libertarian society? The primary social check would be the boycott, and it would be far more effective than any political action ever has been.
All kinds. A state is a compulsory monopoly on initiatory force. Such an institution is, by definition, unlimited in function, no matter what “the law” says it may and may not do.
I suggest going here and educating yourself. I especially recommend anything by Rothbard, for starters.
Okay, but you ought to realize that no government, no matter how constituted, will ever give a rat’s ass about what you think America stands for.
Yes you are. That is not name-calling, it is a fact. You want a state; you are a statist.
So do I, but I realize that the concept of “our country” has absolutely nothing to do with the government that taxes it.
First, it’s not “our” consititution. It’s their constitution.
Second, to paraphrase Lysander Spooner, whatever tyranny the Constitution did not itself approve, it has been utterly powerless to prevent. It is, as George W. Bush observed, just a goddamned piece of paper.
Third, the Constitution was never intended to protect liberty. It was the result of a successful coup by statists who found themselves disenfranchised when the colonies won the war. It was illegally foisted upon the colonies without the consent of their peoples, and has ever since been an instrument of plunder for the policial class.
