It looks to nearly everyone that the world of academia, especially the colleges and universities, is infested and under the total control of the Fundamentalist Left.
It doesn't look that way to me.

Why? Because I reasoned long ago that the goal of education and educational institutions is to be the keel of society, to be the drogues (the sails thrown over the stern in a storm to stay aligned directly into the waves). Educational institutions are designed to be ultra conservative... conservative meaning unchanging or changing very slowly.
So what is going on now where Noam Chomsky is still the hero of academia?
Academia is holding on to the anti-American, anti-war values of the mid 1960s, when most faculty members were coming of age. Think Jane Fonda, Hanoi Rose.
Simple. There will be no change in academia until the current old yippy-yuppie crew dies off.
