I think you are right and to add to it, I think Kerry had political ambitions when he went to Vietnam, I think he saw action and was revolted by the reality of it. I doubt that he ever got over it. While (and this is a stretch) he might have been well intentioned in his criticism of war, his actions hurt his country and his comrades.
He was wrong and he has to deal with the consequences.

Thank you. Very reasoned response. You may be correct that when he encountered the reality of war (which is traumatizing), he never got over it. And .. you are correct that although America does allow him to protest, his actions did harm America and the military.

So far, I don't think he's dealing with the consequences very well.
