Why are so many Americans unable to tell the difference between right-wing and left-wing?

[Glenn Greens]

It is obvious to most educated, first world people outside of the USA, that many Americans have no idea what "left-wing" or "right-wing" mean, either in today’s context or historically. Is this a product of decades far right-wing corporate media propaganda (eg McCarthyism etc)? Is their grossly mismanaged and under funded public education system to blame? Is it cultural and related to the confusion working class Americans have between "working class" and "middle class"? Apparently the US mainstream media completely omits the real political left, and substitutes with center-right posers; faux-left mouthpieces for capitalist parasites. When was the last time you saw an actual socialist disseminating socialist understandings in the mainstream US media? I've never seen it personally. Will social media ever be able to inform enough Americans to counter the influence of mass media propaganda from the moneyed elitists that dominate American plutocracy and brainwash the masses?

PS> I'm not interested in moronic complaints about grammar and spelling; Einstein was dyslexic and could not spell; but what he meant is discernible to those who are informed and can use their brains properly. So if you don't understand me, that's your deficiency not mine. I don't use bastardised American grammar or spelling; get over it.
