They are indeed.
They are becoming Postmodernists (i.e., nihilists, anarchists, deconstructionists).
They realize that communism doesn't work as a system of governance (there's plenty of proof of that all around the world) and are now satisfied to deconstruct/destroy everything that does work in the standard Postmodernist way.
The modern incarnation of Communism IS an amalgamation of nihilists, anarchists and deconstructionists.
What This Guy is suggesting is that some true believers in the Donkey Party (such as RFK Jr., Tulsi Gabbard) are beginning to see the light. They’re responding by apostasizing from the ranks of the “Cloward-Piven”-worshipping nihilists, anarchists, deconstructionists and Alinskyites and are joining the rest of us in the land of the living.
