Right-wing propaganda + a lack of economic opportunity + a lack of critical thinking skills = fear, hate, and violence
For decades now, good American jobs have been sent overseas to enrich wealthy CEOs and shareholders; tax breaks have been given to millionaires & billionaires (while the middle-class & poor have been saddled with more and more debt); bankruptcy relief has been savagely restricted for lower-income groups; our health has been the victim of constant political games; our wages have been stagnant and our retirements have been jeopardized; investment in public education and higher education has been curtailed; the tax burden has, and still is, being shifted from the rich, at the federal level, to the middle-class & poor at the state & local level; children from middle & low-income families are drinking lead; and the list of persecutions and neglect goes on and on and on.
Beware the libtards!... and other bogeymen that distract us from the rigged economy...
"Rupert Murdoch's Fox News channel and right-wing radio have preyed upon those who've seen their American Dream go up in smoke. And they have helped to create a generation of angry and violent conspiracy theorists who will believe any lie that is perpetrated on those airwaves."
