There are no “right wing militias”. We all know better than go near such a thing. We’re one to try to arise it would be flooded with gummint agents. In fact, once they got out the “secret handshake” they would probably discover they were ALL gummint agents. That would sure be one hell of a funny moment. Of course one could advertise they were starting such a thing and then just “process” everyone that showed up.
The right wing milita is anyone who isn’t a democrat and owns a gun.
Any “right wing militias” are simply legit gun owners in other words using their 2nd Amendment rights.
