Slow Drip Demoralization and Propaganda Did this
Look around you. The american left is proving that "the Big Lie" is an effective tool in swaying public opinion towards falsities. It's an effective tool to win over people's hearts and minds, despite the facts, irrespective of how widely availalble they are (they have the same Internet we have,. which is a level playing field)
The US left. RIGHT NOW. Is looking almost identical to the pre-nazi german underclass. Disenfranchised by Industry and anarchocorporatists, while being fed--inundated by magical thinking, occultism in the context of an ever-increasing Godlessnesss, Atheism, nihilism--at the time of the early 1910s germany, because of the dark german philosophers.....today in America, because of NETFLIX and growing anti-Christian, anti-FAMILY (attack the father via feminism) sentiment
Look around you
The left is the pre Nazi party. They have all the same behaviors. We've reached "Peak Projection" in the "Party of Projection" when they call Trump supporters "Fascists"
IN fact they don't even know what that means, because if they did and if they were honest, they'd realize that THEY are the fascista
The party of the CIA
Useful idiots, tools, mouthpieces and parrots of the mainstream CIA run mockingbird media talking points and narratives; fulfilling the overall strategy of the perennial war complex and globalism generally--leading to a vast, technomanaged, cybersteered, low information, low choice, opportunity-limited, technoneofeudalist underclass in a unipolar government simulation of reality (Orwellianism)
The argument that Progressives, and those to the left of Progressives, share socialist ideals with the Nazis, is pretty correct but your blanket admonition is a bit hyperbolic.
The socialist revolution never happened in the United States. Probably because the working class looked around and realized that their lives under capitalism really weren't that bad compared to under-industrialized countries and third world shitholes.
Having failed at violent revolution, the Marxists reconceived their mission and infiltrated the institutions of the West - The social, academic and political.
Rebranded now as 'Social Democrats' they seek to demoralize the West to a degree that the populace will vote themselves into socialism democratically.
The closest comparison with the modern Progressive Left and Nazis, imo, are the Hegelites who believe that violence is justified to obtain political ends.
These are the Antifa faggots.
Perhaps some blood will be spilled. But we'll be fine.
