That's an absurd oversimplification, especially since communism didn't exist at that point.
Although the poster went a little overboard on his essay, his premise that the pilgrims did not represent the American way (at least as it is historically represented rather than what flows from Washington today) is fundamentally correct
No, he referred to the Puritans...one or more generations removed from the Pilgrims, AFTER the crops began to flourish and the corruption of the English church became apparent. The essay is devoid of supporting fact and represents nothing more than mimicking what he/she has been taught in school about the "insensitive, judgemental Puritans."
