You mean like Q Anon? That decentralized cult ended up storming the capitol a few years ago. Or maybe more like the NXIVM cult that still operates despite its leader being in jail? Or Scientologists which have successfully infiltrated many parts of Hollywood?
This is specifically why I’m convinced that the insurrection act is going to be invoked at some point, and then a bunch of the conservative militias will “pop up out of nowhere” and get deputized. And just like that, you’ve got your home-grown all-American neo-Sturmabteilung.
