DR3 (Democrats aRe the Real Racists) exists because blue-pilled Republicans and conservatives accept the Cathedral's metanarrative. They accept the location of the Overton window and try to occupy the right-most territory within this framework.
Once the Cathedral lost narrative control in 2015 and 2016, the Overton window shifted right. The consumers of the old official narrative don't understand what's happening. Now some leftists have found themselves lost in this new narrative playground. Republicans are the Real Communists (3RC) looks like good anti-Russia propaganda, in the same way that Democrats are Real Racists looks like anti-racism propaganda. As the red-pilled know, this doesn't work because racist = white. Even if you score a small point against a Democrat, you have accepted and advanced the frame of racism being a grave sin, and since Democrats control that narrative space and define racism as being white, blue-pilled right-wingers end up losing the war.
Similarly, with a communist winning election in Bronx and Democratic Socialist (communist) candidates running in various places, it is ironic that the left is simultaneously running anti-communist propaganda.
I don't think this will have much impact because leftists are retarded children who don't know anything about history. It's all rhetoric to them. But they've inadvertantly blown open a troll hole that may be difficult to close.
Meme warriors, this is your challenge: create the most stridently anti-communist meme possible and get Democrats to spread them everywhere.
