Yeah, so? If a group of "neo-nazi" tags along, that makes everybody a neo-nazi (much less so, a nazi danger, as neonazi is more like a kind of "edgelord" archetype for far-right leaning people).

If a group had the hammer and sickle or Mao or whatever on their t-shirts on a democratic side protest would it make the people there "communists"?

Or would mean anything about some "danger" to the US of communism becoming installed?

US was, is, and will remain corporatist and capitalist. Democrats, Republicans, and Liberalists all agree on that, and even if they didn't, tough luck, it's not them that have the power, the corporatist elites do.

There is as much "danger" of a fascist coup as there is of a communist overtaking, or as there was of Obama being a radical pro-Black president or Trump "draining the swamp": zero.

The rest are talking points for masses with nothing better to do (and pundits that make money of it) to hit each other with.

My european 2 cents.
