Boortz never actually delivered this comencement speech, which he wrote in 1998 to protest never having been asked to deliver one. Here's a sample of it:
Now, I realize that most of you consider yourselves Liberals. In fact, you are probably very proud of your liberal views. You care so much. You feel so much. You want to help so much. After all you're a compassionate and caring person, aren't you now? Well, isn't that just so extraordinarily special. Now, at this age, is as good a time as any to be a liberal; as good a time as any to know absolutely everything. You have plenty of time, starting tomorrow, for the truth to set in.
Over the next few years, as you begin to feel the cold breath of reality down your neck, things are going to start changing pretty fast... including your own assessment of just how much you really know.
So here are the first assignments for your initial class in reality:
Pay attention to the news, read newspapers, and listen to the words and phrases that proud Liberals use to promote their causes. Then, compare the words of the left to the words and phrases you hear from those evil, heartless, greedy conservatives. From the Left you will hear "I feel." From the Right you will hear "I think." From the Liberals you will hear references to groups -- The Blacks, the Poor, The Rich, The Disadvantaged, The Less Fortunate. From the Right you will hear references to in dividuals. On the Left you hear talk of group rights; on the Right, individual rights.
That about sums it up, really: Liberals feel. Liberals care. They are pack animals whose identity is tied up in group dynamics. Conservatives and Libertarians think -- and, setting aside the theocracy crowd, their identity is centered on the individual.
