From ThinkProgress, a very disturbing image from a gathering of very disturbed and dangerous individuals:
Sign reads: "Warning: If Brown can’t stop it, a Browning can"
This is the type of violence that the Republicans and their anti-American supporters have been striving for ever since the Obama Administration took office with the pledge to clean up the GOP's mess.
In attendance and apparently proud to be part of a group of anti-American traitors engaged in seditious behavior were Republican Reps. Steve King (IA), Michele Bachmann (MN), and Mike Pence (IN), and the insanity was in part organized by Dick Armey's Freedomworks and Art Pope's Americans for Prosperity. Americans for Prosperity "advocates pro-tobacco industry positions on issues like cigarette taxes and clean indoor air laws" [SourceWatch].
The Tobacco Industry was a major player in the efforts to astroturf the previous attempts by the Clinton Administration to pass healthcare reform, and it appears that the efforts -- and lessons learned in how to game the system -- have not been forgotten.
With the advent of signs advocating gun violence if and when HCR passes, however, the rabid fervor of the lunatic fringe takes a very dangerous turn into deep waters, where advocating violent insurrection and fanning the flames of insanity are likely to initiate a powderkeg that just might backfire on them...and on their Republican 'leadership' in Congress.
