The SBVFT are a bunch of partisan dousch bags. They are a bunch of bitter Republican pills who can't get over the fact that Kerry joined thousands of other Vets speaking out against the Vietnam war when he returned from service there.
I nominate them collectively for this year's "Biggest Douschbags in the Universe" award.
The amount of evidence discrediting the Swift Boat Vets for "Truth" is overwhelming, I have only provided a small sample here. It seems to me they should rename the organization "Swift Boat Vets For Falsehood"
