One data point? Not very convincing.
Not one data point, but millions. Only the fringe nutjobs, a few thousand, participate in this shit. Even if a few of those Fields ran down were completely innocent bystanders, in the future, it will only be the nutjobs....including Jerrod Kuhn, just like he's done before.

Not following you.
There have been times in history, when these types of movement instead of remaining small, or whithering away, instead grew and become more violent causing terrible harm.
What leads you to conclude that it is not possible at this time?
Agreed, but notice that those events took specific requirements to come to fruition. Look at Germany after WWI; the Treaty of Versailles not only put the entire fault of the war on Germany, but made them pay for it. The Treaty broke the economy of Germany. It was such overkill that the US refused to sign it.
Germany, destitute from the Treaty, missing an entire generation of young men and much of the country shattered was in severe pain. Out of chaos comes order; usually not the good kind either. The US was unique in having a revolution which didn't turn into a dictatorship. France wasn't so lucky and Germany's conditions were ripe for a dictator.
The US today doesn't have those conditions. Most people are happy at home but uncertain about the future, especially for their children. They have jobs (that don't pay well, but pay), they have homes (not the greatest, but secure) and they have both food and entertainment. You won't see a ******* Nazi or Socialist Party takeover of the US until current conditions in the US are more like Germany in the early 1920s.
