And in that Constitution, there is no such insertion anywhere within involving a function to "progress with the times." There is no Article or Amendment that indicates that the government may stray outside the Constitution for that alleged "progress", and in fact every limitation, and check, and balance, upon the government, is to prohibit the government from forcing tyrannous dictates upon the citizenry under the guise of "progress", or "kindness", or "modernism", or any other rationalization seeking to empower government, or a faction of fellow citizens, over other fellow citizens, and enslave them to their agenda, which is what is going on in this country at this time.
In fact if you had actually read that Federalist #10, which you previously cited in error, you would see that Madison is actually providing an apt and accurate description of Progressiveism/Marxism.
Madison
nails this description immediately following his discussion of the violent deaths Democracies enjoy by describing:
Theoretic politicians <today's "elitist politicians"> , who have patronized this species of government, have erroneously supposed that by reducing mankind to a perfect equality <social justice> in their political rights <thereby fabricating rights to enslave>, they would, at the same time, be perfectly equalized and assimilated in their possessions <redistribution of wealth>, their opinions <political correctness>, and their passions <social engineering>.
Here Madison is
absolute prescient in his description of Marxism, decades before Marx ever put pen to paper, and your so-called "progress with the times" of today's Progressive movement, is nothing more than repackaged Marxism, an ideology that employs the factionalism born of mankind's less reputable traits of sloth, envy, and greed, in order to enslave mankind to his brother, in a shared misery under the direction of a tyrannous government.
Madison recognizes our constitutional republic as the cure for that factionalism, and describes that "progressive" mentality as,
"destroying the liberty which is essential to [this country's] existence". In other words, it is enslaving one portion of man, to a few men, and doing so by tyrannous government dictate. When this country no longer guarantees liberty, and exists in name only, as is true now, then there is real and legitimate cause to secede.
Perhaps it is not that Madison was so "absolutely prescient" as the fact that there is absolutely nothing at all "progress[ing] with the times" about the current ideology. It is no coincidence that today's "Democratic" party is advocating such a corrupt scheme.
In fact our Constitution was intended to protect us from just such democracy, and specifically protect us from the application of just such corrupt and tyrannous schemes as the government is now intending to apply to us, by having transgressed well outside of the Constitutional authority.... hence the reason for secession.
There is no such "power grab" in what I and others promote, but rather a power denial of an illegitimate exercise of power specifically prohibited by the Constitution, and a restoration of our government and freedoms to what was intended.
*OUCH!*, you really walked into a wall this time. It's gonna leave a big mark! Perhaps next time you might actually consider understanding what sources you reference, before you reference them and argue their content.
