As a poster at Vox Day’s blog noted it is the communist organizations who are fomenting this anger in order to make black communities yet more ungovernable hence making its residents more miserable. The old worse is better strategy of the commies, and lo and behold President Camacho (Obama)is helpling.
I also think there's a reason these outbursts are happening mostly at malls and places of business: it's meant to cause financial damage to merchants engaging in capitalism. That's why it's not taking place at schools or churches.
Of course, the only real effect is likely to be that middle and upper class whites and Asians will increasingly simply shop online (which requires a credit card. Which requires credit.) And fewer retailers will maintain a physical presence. The poor will find themselves with less and less to choose from, and only cheaper, lower-quality goods. The accoutrements of middle and upper class life will become more or less invisible to them.
After WWII, we had a Ukranian immigrant move into our apartment house in NYC. Even as a kid, I was interested in history, so I started pumping him as tactfully as possible. (We had a lot of vets who didn't want to talk about their experiences.)
After a while he opened up. He was a Communist partisan and killed quite a few Germans. He quit being a Communist (but kept on killing Germans) after an incident in one village.
The partisans had killed the last German commandant of the garrison there and the Germans just installed another one. This guy must have slipped through the net, because he was a decent and humane man and treated the villagers better than the last guy.
Soon the vilage calmed down and while not fully cooperating with the Germans, they didn't hassle them. Things got quiet. The Communist group our immigrant was in said that that wouldn't do, so they killed the good guy.
Another replacement came in and he was more true to form - executing a few locals in retaliation to prove the point. He soon had the villagers enraged enough that they went back to supporting the Communists and all was well. He said it was then that he realized the Communists weren't for the people, only for their own power.
History repeats - or at least echoes.
