NRO STAFF UPDATE: See here regarding a controversy over the final quote in this post.

Edward Glick, a professor at Temple University, recalls how in the space of 40 years:

American academia has been transformed into the most Marxist, postmodernist, know-nothing, anti-American, anti-military, and anti-capitalist institution in our society. It is now a bastion of situational ethics and moral relativism, and it teaches that there are no evil people in this world, only oppressed ones. American academia is now a very intolerant place.

Glick looks back at August 1968, when anti-Vietnam War protesters crashed the Democratic convention in Chicago and then went on to effectively dodge the military draft by staying in college. As well-documented by Roger Kimball and others, many of these leftists went on to graduate school and took over the humanities and social sciences by gaining control over the hiring and promotion processes.

In other words, the Left seized:

the power to influence their colleagues who want raises, sabbaticals. grants, promotions, and tenure. One of the best ways to influence students, colleagues, and the citizenry at large is to hire, promote, and tenure only those people who agree with you.

Glick offers an example from Duke University to show just how brazen and arrogant this power-grab has become:

The chairman of one of its major departments was once asked in a radio interview if his department hired Republicans. He answered: “No. We don’t hire Republicans because they are stupid and we are not. Why should we knowingly hire stupid professors?”
