The left is only outraged by moral behavior, true patriotism, capitalism, and Christianity.
Remember, most of the left was FOR the North Vietnamese, they WANTED THE NORTH TO WIN !!! Thus, it is a good thing that Kerry helped the righteous North win their war of liberation. I heard this repeated by a Dem apologist only last week. I think it was on MS-NBC. He said something like "the Vietnam War was an illegitimate war, it was an illegal war, and America was wrong to be there and wrong to fight it".
THE QUESTION FOR KERRY: "Are you glad the North Vietnamese won the war?"
