This is not a story that proponents of the Iraq War will find comfortable. Here, have a look.

Meet a parent whose child -- a 20-year-old son, to be precise -- spent two years in Iraq and sustained a catastrophic brain injury. That's his photo on his dad's placard. The name isn't important; there are thousands of parents in America whose children have suffered the same fate. Many of them have banded together, as did this gentleman and his fellow protester, in an organization called Military Families Speak Out.

I'd like to see advocates for the rightness of this war explain to this man why his son's life had to be ruined beyond hope of repair, and what platitudes about freedom, terror, fighting-them-there-so-we-don't-have-to-fight-them-here justify a young life destroyed as surely as if it had been ended entirely.
