"Can a people be more ignorant and brainwaished?"
I don't think so.
It's a Marxist's dream. An ignorant, brainwashed, MOTIVATED base.
You two don't spend much time with college educated, mostly caucasian, liberals do you ?
These people have a certain type of intelligence. They can take some facts and use some degree of logic and draw conclusions.
What they are unable to do is reconcile these conclusions with the real world that often is not logical. Further, since they are "the smart ones", they often do not understand that their facts are incomplete, their basic premises are false and therefore their conclusions may be wrong.
Their idiotic conclusions have no relevance in the real world, but their arrogance precludes any reevaluation.
