Beacause it's in their nature.
Personally, I think the only thing to do is to start new institutions of higher education, such as Tom Monaghan's Ave Maria University (now in Florida).
But what I really and truly wish is that we could get these lefties out of the state systems, at least. Even if I never intend to go to one of the state universities or send any child or grandchild to them, my tax dollars go to support them. It upsets me greatly to know that I'm supporting a bunch of smug, self-satisfied (and lazy, tenure-seeking) creeps who hate and attack everything I and most Americans consider valuable.
But to further my point, what we are in today is an economic war. These terroists have attacked our economy and our sense of certainty. But make no mistake those who run our country, whether Liberal/Democrat or Conservative/Republican believe that we can change the world through economics, or trade. And that means that they believe that on this point Marx was right; economics is everything.
We are like the Liliputians who continue to argue about which side of the egg to crack. Communism is dead and Industrial capitailsm is dying. But it is too difficult for us to see that fact because we all believe in Darwin, Freud and Marx. Until we become un-educated we will all continue to bicker about who is worse than whom. Commercialism is just another form of collectivism. And it is obviously killing western Christian culture.
