I guess this is a uncomfortable subject right now.
Could you be a bit more specific? The question is phrased a might vaguely/broadly.
But to proceed, when we speak of anything political, we are speaking of human relations. Therefore, the central pillar of any "movement" pursuant to proper liberty must found upon proper human relation.
The nature of what we are
in relation to one another pretty well spells out the totality of our concerns with respect to the notion of "liberty".
If we all hold equal claims to life, such as they may be no matter how strong or tenuous, then it becomes instantly clear that no man is born to be servant to another, nor master.
The rest follows therefrom in the most intuitively obvious fashion imaginable. That is, it is obvious to those who are of a proper bent with respect to liberty, and in order to be such an individual, one must have the qualities of the Freeman, eschewing those of the Weakman. What are these qualities? Nothing more or less than courage, understanding, and the integrity to live by what one knows to be right; to hold sacred the Right in favor of the Wrong. It ain't rocket surgery. It is, however, and endless challenge in the face of the endless temptations that bid one abandon his status as a Freeman.
To that last point, what might those temptations be? They are nothing more or less than anything that leads one to the desire of trespassing upon their fellows. Once again, the truth it simplicity itself.
Simple are these basic guiding principles, yet their practice is often fraught with difficulty. Why? Because men want what they want and those desires often run strongly against the proprieties of proper human relations.
Example: your neighbor has a fine and gorgeous wife. If you get to thinking about her too much in ways you know to be "risky", you end up going down a path that strays from the proper virtues of the Freeman. You start thinking all manner of inflammatory thoughts and because your thoughts form your reality, one cannot help but to follow where they lead, unless you cut them off before it is too late. Thinking about all the things you would do with and to your neighbors beautiful and fair wife can serve no good purpose when taken beyond mere passing fancy. To interject yourself between the parties to a happy marriage is unbecoming of a Freeman, smacking of the lowbrow thief who has no respect for even himself, much less anyone around him. It is not to say that one cannot find the wife of another beautiful and charming. There is no sin in wishing she had been yours, or any of the other mild and passing regrets one might experience. But to cling to and cultivate such emotional attachments is the mark of the Weakman and all I can suggest is that one not go to such places because it invariably causes gratuitous and unjust trouble.
The path of the Freeman is rarely easy. The path of the Weakman, requiring little of him beyond running endlessly after his undifferentiated lusts, is ultimately unsatisfying and endlessly boring, not to mention potentially very dangerous to himself and those upon whom he foists his perfidies.
The "parameters" of the Freeman are few, simple, intuitively clear, complete, sufficient, and almost never quite easy. But for the effort one is rewarded greatly, if only he is willing to see it. Alas, the Weakman is not. The saddest aspect of being a Weakman is that he chooses his status. Nobody forces it upon him and, save in very rare cases, there is no organic basis for the choices he tends to make.
We live in a world of Weakmen. It was designed for them. It caters to them. It beckons to all to join the drab, grey, suicide-inspiring dullness of Weakman culture in its false promises, held out as bait for the feeble-minded and corrupt.
While the parameters comprise a small body of simple ideas, learning to apply them is rarely easy, for it requires both broad and deep understanding of what is right and what fails. It requires the will to accept truths that are in some cases endlessly unappealing, which the Weakman stoutly refuses, often with great tantrums and brattish noise. The so-called "progressive liberal" is the textbook example of the Weakman, but many on the so-called "right" carry plenty of failings - enough to qualify them as Weakmen.
Principles and theory: easy. Practice: pure art, often difficult.
