The people we see all around us are hordes of Useful Idiots, designed to be fully exterminated immediately after the success of their own resolution. Their sole purpose in life is to marched into the machine guns by their overlords. They are a slave army.

By any Leftist calculation, the US should have been a fully Communist state a hundred years ago. The Marxists would have assumed the ascension of the Progressive Era would have led to a Socialist state by the 20's. It's not like Communists weren't trying to turn the country into a Communist/Socialist state. However, WW1 broke the entire Marxist Metanarrative. Lenin tried to explain that the cause of this was that the Proletariat were the most reactionary force of all. The Socialists split into warring factions, particularly in the US, as the Progressive Racialists sided against the Communists' class-focus. The Progressives effectively "Rode The Tiger" of the early anti-Communist backlash of the early 20th century, and let the Communists take the hit.

As the new crop of post-Marxist Leftists (The Old Left) seized power in Europe, while Fabians infiltrated their way in through the State Department. The Fabians felt that the Marxist Metanarrative couldn't be fulfilled without much slower subversion, and then a proper revolution could take place. The Soviets, even at this point, would work with the Fabians to subvert the US and cause it's Liberal and Republican institutions to collapse. Unfortunately, anti-Communism was still popular in America, so Democratic & Fabian Socialists like Roosevelt had to enact Socialism in all but name, using war as a justification. That being said, the intellectual circles of America were already fully subverted Leftists. Going all the way back to the Progressive era, the American elites were always willing to shower people with tales of the success of Socialism and Communism, and how strong those countries were. Every unionist, every bureaucrat, every academician, every journalist, every author, every entertainer would simp for the revolution, as a Useful Idiot to break the American people's values and will. Again, this lead to Anti-Communist blowback in the 50's.

The Frankfurt School and it's decedents (The New Left) focused not only on a Fabian seizure of institutions, but on the subversion of people themselves into becoming the thing that Marx described as the "New Socialist Man". Cultivating, grooming, people into Socialism. They also decided to drop Progressive Racialism as a mechanism to power in the west since they had smeared National Socialists so thoroughly. Where Lenin's old Left style simply seized on a coalition of the margins to seize power with violence and force, the Fabians and the Frankfurters were going to work at grooming everyone into being more inherently Socialist. Even though basically every institution would have welcomed further state control anyway. There still needed to be more subversion, over every facet, of every life, because it wasn't enough to kill what Lenin called "Private Capitalism": the innate individualism, and liberalism of free persons, particularly Americans.

And although the Fabians gain some ground culturally, they have to allow a Liberalization of American institutions away from FDR's Democratic Socialism of the 40's in order to politically and monetarily profit off of their gains. But the constant subversion, from both Fabians and Soviets, created the 70's radicals who are the worst parts of basically every Leftist faction. As authoritarian as the Soviets, as insidious as the Fabians, and (in the case of the Black Nationalists) as malicious as the Progressive Racialists of previous eras. Their violence and general incompatibility with the rest of humanity made them wonderful Useful Idiots, but also generated the inevitable blowback that gave power to Goldwater, Nixon and Reagan.

Now that the Fabians are aging out to the brink of death, and the 70's radicals are in established power structures, they have cultivated the most fully subverted communist simps in the fucking history of Leftism: Millennial Leftists.

What I'm saying is that every single iteration of Leftism has attempted to subvert American values and "Private Capitalism" harder and harder with each passing decade, but we've reached a point where the people who are supposed to command the Useful Idiots to march into the machine guns are fucking dying. The Slave Army has to have a Master. Instead, no one is in charge, so we are facing hordes of wandering subverters who have no one to command them. Their all waiting for a Stalin, a Mao, a Lenin, a Trotsky, a Tito, a Castro, or a Pol Pot to lead them to their deaths. Instead all they've got is Biden, because even Bernie is too weak to lead them. And don't think that the Communists in China have it all figured out either. They too are actually encountering cultural subversion, the feminization of their men, and rampant productivity. They call it Gen Zen.

What I'm trying to say is that the Left has been piling subversion on top of subversion on top of subversion for so long, they accidentally built a Doomsday Machine. In a proper Communist Revolution, every Critical Theorist, Queer Theorist, Gramscian, an Alinskyite would be put against the wall and executed within hours. Instead, they Useful Idiots have become ideologically posessed automatons (NPCs) destroying every semblance of order in their path, and fueling the destruction of one rule set into momentum to subvert and destroy another.

What the Twatter in OP's post is realizing that the Millennial Leftists are not even really Communists, but simply a force of destruction in and of themselves because they are a leaderless weapon, destroying everything in search of Utopia.
