Still seems like plenty of people on the left are around in the US who aren't trying to live out their revolutionary fantasies and are trying to work change in a "calm" manner. Heh, for "garbage people" it's basically the Broken Windows theory - and people burning stuff and looting are garbage (there's a famous More quote on this). Hm, I am not sure if force wouldn't work, in theory, though I guess it'd reach levels of war crimes to strangle them via food and water or just killing them Roman style.
Not sure what the solution would be to this though, in terms of a practical one, being outside of the US.
