I absolutely agree with this Hillsdale College professor (h/t Instapundit).
If we are to comprehend what is going on, we must pay close attention not only to what Obama says but to what he conveys in other ways. His tone is nearly always moderate but what he hints at and what he intimates by way of body language often convey the opposite. Witness his warm embrace of Hugo Chavez. Behind the thin veneer of politeness, there is, I suspect, something ugly lurking. In the first of the autobiographies that he claims to have written, Barack Obama frequently speaks of himself as being in the grips of rage. We would do well to take him at his word. If we are to stop him from doing great damage to this country and to our friends and allies, we must take every opportunity that comes our way to unmask the man.
Go, read it all.
