That is eating at Cindy. She hated what he came to represent and her deep set anger and conflicting emotions are eating her up. Sadly, she has given herself over to the dark side and now supports everythiung her son was against, including her support and kind words for the very people who killed him.

Who Does Cindy Sheehan Hate?by Michael Reagan
Sigmund Freud had a concept he called “projection, which has been defined as a defense where the ego deals with unacceptable impulses and/or terrifying anxieties by attributing them to someone in the external world.
In many ways I think that explains the behavior of the media’s current patron saint, Cindy Sheehan, whose hate rhetoric aimed at President Bush is really meant for someone else who she can’t admit even to herself is her real target. To do so would represent one of those “unacceptable impulses” Dr. Freud was talking about. In this case it could well be that Cindy Sheehan is projecting her rage at George Bush when the one she really despises is her late son Casey, who died as a hero in Iraq, precisely because he did die a hero in Iraq.
The more I listen to Cindy Sheehan and consider her past actions and her past words, it occurs to me she has always been a liberal, she’s always been anti-military, and she’s always been anti-Republican. It appears that she raised Casey in such an environment, yet despite that what does he do? He not only joins the military engaged in a war she bitterly opposes, but to add insult to injury when his enlistment runs out, he re-enlists although he knew that by so doing it meant he would be sent to Iraq where a war his mother despises is being fought. .................
I love Michael Reagan. Very smart man.
