Except for some African Americans and some Antifa we do not know what we have. And the ones mentioned are on the left. Crossing the line when it comes to violence is when we all will know. Either way I see no support to save cities and Blue areas from those who from Red areas.No person knows their fighting capacity until forced to fight.
That being said more people on the right have prior military training, as well as weapons training.
And people on the left are more apt to submit to power, so I would think you would get more Quislings from the left than the right.
Most people under occupation just try to get through the occupation.
