I think this point has been vastly understated since then.  This phenomenon represents a large factor explaining why there is such momentum behind state worship in our time.  On those occasions when I have been allowed to have in-depth conversations that get to the roots of people's undying devotion to statism, I often hit a common nerve after most of the logical reasons to oppose statism are admitted to.  (Getting to this point is rare by the way since anger, silence, and blank stares are the usual reaction when there is no defense to an indefensible position.)

The struck nerve relates to a deep-seated reverence that many people maintain for their ancestors.  People want to think, "My daddy was a good guy."  Their uncles were good guys.  Their grandpa was a good guy.  They were spiritual.  They were honest.  They worked hard.  They told the truth.  They were respectful to others.  They would help someone in need.  Therefore, certainly, they would not have committed a chunk of their lives to something unjust.

Usually the unchallengeable position revolves around Daddy's or Grandpa's participation in WWI or WWII (or Vietnam, Korea, etc).  Ron Paul's opposition to a century of perpetual war is taken as a personal insult directly impugning the family tree of so many people.
