Do we really need to go down the rabbit hole of naming off genocides that communist regimes have been directly responsible for? Why would you want to pick any of those three options? They're all horrible. That's the point. Antifa and the nazis are the opposite faces of the same awful coin. Both groups represent collectivist bigot ideologies who, at the core, can't stand that some group of different people with different ideas exists.
Most of us are just watching from no position wishing you'd just kill each other off. It's bewildering you (and antifa) have taken this position of with us or against us in an attempt to shame people into the cause. It dumps gasoline on the fires of righteous outrage the average american feels when they get called something they aren't.
You know who you sound like when you use conspiracy theory crap like this to make a point? A gun toting right winger... better start stockpiling before our nazi supporting government comes to haul you off in the middle of the night. /sHell...If the current government that is in bed with the Alt-Right
