We have a federal government in these united states now known as "THE UNITED STATES OF AMERICA, INC. aka THE UNITED STATES Inc. It is a corporation formed with the Organic Act of 1871. Corporations exist for profit. Corporations are managed by their President/CEO, the board of directors and the stock holders. Corporations operate to perpetuate corporate profits and to perpetuate the corporation itself. Corporations do not exist to benefit outsiders, customers, nor employees nor do they answer to any of these groups.
Corporations are set up to provide limited liability to the stockholders for the corporate actions or inactions. They exist to benefit the stockholders and shield them from liability which might result due to their action or inaction. The corporation appoints its board of directors, CEO/President, Secretary, and Treasurer. The customers and employees have no say in that selection. It is up to the owners/stockholders.
There is very little in the above that most people do not already know; with the one exception that perhaps you did not know the U.S. government is a corporation. I cannot speak for others, but I know that I do not personally own any stock in this corporation hence I have no real vote nor say in the management thereof. Perhaps you do. I suspect, however, that you do not because I do not know anyone who does; though I confess of the desire to know who the stockholders are.
We have in place a corporation for a government which is "of the corporation, by the corporation, and for the corporation"....as with all such organizations. The corporation has assigned/appointed the supreme court justices to endorse their corporate policies and declare to the public that they are constitutional, and the congress/board of directors has steadily relinquished its powers to the CEO/President to operate as the corporate decision maker with Executive Orders. You do not need to wonder why they are not responsive to the desires of the people.
One has but to consider the basic structure of the system to understand how our country has gone so far off track and why. Anyone who protests, resists, or is opposed to the corporation threatens the perpetuation of the firm and is therefore a threat aka "potential domestic terrorist." A constitutionalist is such a threat because corporate policy and decisions which benefit the corporation run counter to the adherence to the constitution. Therefore to be a constitutionalist is to be anti-corporation which is to be seen as a threat to the perpetuation of the firm. Former military are thus classified because they took an oath to uphold and defend the constitution from enemies both foreign and domestic.
A domestic corporation seeking to overthrow the constitution and instill in its place corporate policy might well be viewed as a domestic threat.
