Easy killer. I think he saw it on Facebook and is asking our opinions. The info under the picture is quoted from Facebook.
AZRH fell (accidentally?) into the same tired argument that the left automatically resorts to whenever Obama is criticized: Obama is black, therefore anyone who criticizes him is only doing so because he's black and they are latent racists, no matter what message their criticism contains.
In this case the criticism is directed at liberals with no mention of race, but with 5 years of the left constantly bombarding us with the race card specific to Obama, it's easy to see how one can accidentally lapse into such an assumption.
Bah, nothing more complex than finally being able to hit someone else over the head with the same club he's been hit on the head with by lefties. Many conservatives/libertarians just love to whack someone else with the "racist" club, too, and jump at the opportunity to swing away. Not the first time it has happened here or elsewhere when discussing politics.
Not every topic that makes one feel uncomfortable because it challenges internal & often subconscious left-wing values/attitudes makes the poster a racist.
A legitimate response from the OP, who didn't even mention race, is something along the lines of, "Kiss my fourth point of contact, or get your head out of your own," in response to the personal attack and violation one of the few APS rules there are.
FTR, I doubt the premise of the OP and doubt cities will be destroyed. If BHO wins
or loses some of his supporters will riot and vandalize. Because that is what they do (see any of the various sport team championships and riots in the WINNING town). I would bet dollars to donuts it is unorganized and confined to their own neighborhoods. At the worst, it will effect adjoining neighborhoods. In the event that such rioters go about the city, it will be largely in blue, "gun-controlled" cities...who will then reap what they have sown.
