The liberal stranglehold on college textbooks and curricula clearly has at least some influence on the thinking of college students and graduates, and this influence shows itself in the attitudes younger Americans have toward important political issues. A typical college student in the United States spends four or more years listening to information and arguments that support a leftist agenda, while being sheltered from data and arguments that might militate in favor of more conservative positions. Since people quite naturally base their beliefs on the available information, a four year diet of information hand-picked by leftists will inevitably have some effect.
This liberal monopoly on the flow of information allows college faculties to promote all kinds of politically correct beliefs, including some that don’t stand up well to actual scrutiny. The gospel of man-made global warming is one such belief. The best way to convince students of the truth of the theory is to “protect” them from all the evidence that undermines it.
Similarly, positive attitudes toward the United Nations are best encouraged by the suppression of information. University professors, like most liberals, are eager to portray the UN as a force for Good; and the best way to do that is by concealing a lot of embarrassing data.
