fair enough, although it seems pretty plausible to me that someone who first supported the war might start questioning the real value of the continued fight after losing a son. Obviously you can't be too shocked when your son dies fighting a war, but you'd at least like the war to have been worth it. WWII for example was pretty clearly worth it. Iraq, not so much, especially since the entire debacle is almost certainly headed for failure regardless of what we do at this point.

I think a lot of people at first supported the war for various patriotic and moral reasons, but as the costs (human and monetary) continue to rise and the apparent accomplishment continues to diminish many of these people are reëvaluating their stances.
