FightOn, I'm not expert, but from where I'm sitting, you may have two choices on OCS behavior:
1) ignore his comments and continue on doing whatever you are doing; or
2) tell him that you disagree and shut the conversation down.
Some of this behavior is just "habit" from attempting to speak up and express themselves when they were younger...but it does get to be annoying after awhile. I don't think you are going to change his behavior and you have to remember...you can't control him or his behavior, but you can change the way you respond/react to it.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
