I knew something was fishy when I read "ordained Presbyterian minister and therefore a pacifist." I was raised Presbyterian, and I know that Presbyterians are not pacifists, at least not as a matter of doctrine. There might be individual Presbyterians who are pacifists. I don't know whether Fred Rogers was a pacifist. Being opposed to the Vietnam War doesn't make you a pacifist.
I like the idea of shattering stereotypes, however. Surely there must be some true stories out there that could make that same point.
