As Edmund Burke said: "Those who don't know history are doomed to repeat it."
Unfortunately, it is also true that: "History is written by the victors."
The socialists were victorious in seizing academia many decades ago, and they've been busy rewriting history and dictating the curriculum ever since.
Judge Bork summed up how the left took over the colleges in his book “Slouching towards Gomorrah”. They began their planning in 1962 with the Students for Democratic Action and they put their communists in place at a number of universities then started the campus takeovers in 1968.
