The author is David Horowitz.
A book review:
The author does manage to find some truly despicable people (mostly affirmed Jihadists, violent anti-whites, and convicted domestic terrorists). However, I find that most people in this book are not as extreme as those and a few choices are extremely laughable*. Also, most of the people in this book did not support the war on terror for various reasons; that coupled by the designation of nearly all the professors as liberals leads me to believe that the author is a dedicated conservative. Which, of course, would lead to bias on all cases, with the skew on people's views getting decidedly more negative the less extreme the case (in perspective).
Another thing that really stood out for me is that the author mentions feminism where applicable and fails to make any connection as to how this is relevant to the professor being dangerous. This lack leaves me with only the conclusion that the reader is to associate feminism with danger. The other thing was the lack of opposing viewpoints. If the author could find so may Jihadists, militant anti-whites, and domestic terrorists; surely he could locate anti-Muslims, anti-minorities, and American supremacists as well.
*Most of these people are proponents of Marxism or Leninism and/or take an anti-American stance. A continuing point made was opposition to the Vietnam war.
