Sorry, didn't see this was a bumped thread. Six months has given us a lot more information.
In Wright’s view, it was important that the enemy understood that Swift boats were a competent, effective force that could dominate his location. To do that, you also had to control the people and their actions; to have them accept Swift boat crews and their authority. You couldn’t achieve that by indiscriminate use of weapons in free fire zones.
It got to a point where Wright told his divisional commander he no longer wanted Kerry in his boat group, so he was re-assigned to another one. “I had an idea of his actions but didn’t have to be responsible for him.” Then Wright and like-minded boat officers took matters into their own hands. “When he got his third Purple Heart, three of us told him to leave. We knew how the system worked and we didn’t want him in Coastal Division 11. Kerry didn’t manipulate the system, we did.”
As for medals, Commander Wright holds strong views: “No one was recognized for completely overwhelming the enemy with skill, courage and bravery. No one wanted a Purple Heart because it meant we had made a mistake. We made sure our crews were recognized, but no one took pride in a Purple Heart. Everyone who served is equally important, regardless of rank or awards.

Your reference, "I just thought of something, maybe Kerry was sent home early because they wanted to get rid of him. ... is certainly true, according to this author.
