Hillsdale College is a private conservative liberal arts college in Hillsdale, Michigan. Founded in 1844 by abolitionists known as Free Will Baptists, it has a liberal arts curriculum that is based on the Western heritage as a product of both the Greco-Roman culture and the Judeo-Christian tradition. Hillsdale requires every student, regardless of concentration of studies, to complete a core curriculum that includes courses on the Great Books, the U.S. Constitution, biology, chemistry, and physics.
Candidly, the implication of the mailing from Hillsdale was not only that socialism is rising, but that socialism has the dread potential to be like one of those waves that could "drown the whole world." Clearly, the mailing wants me to believe that we are in very deep trouble here in the United States of America, if it turns out that socialism really is "rising," and that's what Hillsdale finds out from its survey.
Hillsdale College is not the only place you will hear the claim that "socialism" is coming for us. Name a Republican elected official; that official has almost certainly warned us about socialism. The Wall Street Journal mentions "socialism" almost every day on its editorial pages and in its opinion columns. Did I mention Fox News?
