Once the socialists infiltrated the educational system of the U.S. the textbooks started excluding the bloody and baleful history of communism and socialosm. These fellow has been lured in without a clue about the utterly failed approach to society. As any emigre from the Soviet set of countries can attest Communism is something to avoid at all costs. It sounds good in theory, but takes away incentive, hope and life itself.
A curse on public education...they have been instrumental in the demise of America.
