Whatever happened to liberals?

One thing I have learned by writing columns on global warming the past two weeks is that liberals are less interested in free expression of ideas than in total compliance with their ideas, less interested in critical thinking than in being critical, and less interested in the truth than in their truth.

It wasn’t always so. 
 
In fact, considering that I was raised as a good Democrat and a proud liberal, it pains me to have to admit such distaste for the current state of liberalism. But how can I remain silent when so many people tell me that they agree with my ideas, but are afraid to speak up for themselves because of the names they will be called? How can I remain silent when I have a position of power to defend myself, and I know that young people in colleges across this nation are afraid to turn in papers that contradict the liberal social agenda of their professors? How can I remain silent when there is so much at stake?
