I guess we all can respect folks for taking a stand for what they believe in. In my opinion though one does need to be circumspect regarding their choices. In Ms. Sheehans case perhaps her vision is a bit cloudy regarding what was really important. Example:

In an Aug. 1 interview with the Daily Kos blog, Cindy Sheehan stated, "I have lost almost every friend that I had before Casey died. My husband and I are separated, because he doesn't support my activities, although he knows the war is a lie."

Mrs. Sheehan lost her direction when she failed to be vigilant and honor her sacred trust her vows to her husband. In that regard i find it difficult to respect her.
