As to propaganda being related to empathy.. brown-shirts are people who have been "grown down". They are returned to an adolescent world where all is black and white and they can do things to others and not be responsible for their behavior. Adults become children and start to model after scapegoating and baiting (race, Jew, democrat).
The way empathy comes into the equation is it is empathy (treat others as you would like to be treated, do unto others..) which is the basis of all adult society and all monotheism. Basically it is how large masses of people can work cooperatively together. That is not what George Bush wants. At the WH they like it tribal down in middle America. Where people are after anyone who is not exactly like them (lack of empathy) or people who are different in any way. This keeps the masses busy being led by tribal elders. Too busy and emotionally fulfilled (exhausted) with the fight to get the ten commandments on the front steps or to get all teens to never have sex until they are married. Busy doing a whole bunch of things that don't involved empathy and will keep their heads down.. and not voting for things that actually would be in their favor.
The way to combat propaganda and the renewed adolescence that the propaganda creates is to use adult empathy. To put away childish things and to be discerning (Nancy Grace is very, very discerning... she does not give out her emotions to anyone unless she is dam sure they are innocent). That is what the fighter of propaganda have to do. Be careful with their emotions and use empathy to keep from falling into the trap of fighting adolescence with their own return to childhood and knee-jerk reactions.
