You are of course correct. It wasn't a victory for the pacifists...but don't tell them. I don't think Dean is a communist (yet) because he isn't sure what the word means. I think many idiots start out as useful and idealistic pacifists and get sucked into the commie world view.
I agree that the dem's are leaning awfully far to the left but I think (as I said) the guys at the helm of the party are loooonies (not that purebred commies aren't).
It's a complicated subject. When you have a huge chunk of the American electorate who are willing to allow the enemy to win, and even aid and abet the enemy, without realizing it, it's hard to define who they are and what they are doing. Are many simply idiots? Of course. Are many others actual traitors? Absolutely.
There's a whole specture of stupid-evil leftists in America, and we always have to be careful who we are talking about and in what context.
