As for one of the reader comments connecting this to those of us seeing government as a problem I see pro-government extremists as the problem.
PRO-GOVERNMENT EXTREMISTS
The muggings, knockout game, mob attacks, murders, beatings.. look at the wicked hatred coming out of the White House, the Congress, the MSM, academia against those "who have too much" and how things should be more fair. How "they" stole "the people's" property.
Everyday people are encouraged to react out of being a victim. The employees of the MSM like MSNBC don't have to tell the masses to inflict pain and suffering on the "haves" and take back the "stolen" goods, the masses know what to do to get even and as they do they are cheered by the White House, the Congress, the MSM, academia . . . .
Sounds like a good description of all the miscreants you've named and likewise describes Stalinists, Maoist, Nazis, Marxists and the entire cabal of control freaks.
