I found this video very interesting and it has alot of information that if you have the time you should considering watching it. http://www.youtube.com/watch?v=nN1kp1ggWyM
I suggest combining that video with this video (book if you can buy it):http://www.youtube.com/watch?v=aSF0e6oO_tw
and your memories from the Power of Propaganda exhibit from the Holocaust Museum (if you went).
I think it offers a perspective that is not commonly discussed even amongst "liberal/progressive" groups. Very informational and packaged in a creative video presentation that is palatable to many audiences.
