I take your irony seriously, but as an intellectual drawback.
As Ayn Rand had taught - always use your own mind to understand all concepts involved in a theory you accept (Ron Paul does not care - do what you want, he would say, as long as you believe in liberty.)
For example, rejecting Marxism does not mean it is a waste of time to study it. To make his OWN judgement, one must know
1) why socialism was popular at the time;
2) why it is not workable;
3) why it is still a popular dogma today.
Same with Glenn Beck. People should know why he is more popular than Ron Paul. And why many of his ideas are not correct.
