I never heard of any of the swift boaters "refuting their claims". I believe there were only about 20 of them. They were outraged at Kerry, served along side of him. Kerry to-date has never released his military medical records, to show exactly what type of injuries he received purple hearts for. That is suspicious in itself. As we all know 3 purple hearts & you're out of Viet Nam. Kerry managed to exit Viet Nam 3 months after he got there, which is highly unusual.
