It sounded to me like you were saying Parker didn't want to hear any contradictory ideas.
That's way too much of a blanket statement, and nobody suggested anything so broad. Let's make sure we're comparing apples to apples here:
My own comments were just to say if I am on a team, I expect to be a full member and have my thoughts and ideas respected, not sumarily dismissed because of some ego or prejudice.
These are not team members being summarily dismissed. These were guys more or less coming out of the blue claiming they had the chops to join in on the dives the WKPP was doing, when after hearing about their experience and skill level, (in Parker's opinion) they clearly were not prepared.
My talents and expertise were enough to get me invited, take advantage of them.
Again, not the same situation. If you were on a WKPP team, it stands to reason that you were there for a purpose, and your contributions were welcomed and appreciated. If you were not invited and not part of the team and just showed up expecting to be welcomed with open arms by virtue of being you, you were likely to be disappointed. If you don't agree with the last sentence (hey, what if a Diving God showed up at the door, right? You wouldn't want to dismiss a real-life Diving God, would you?), that's a valid opinion you're definitely entitled to hold and defend, but it's not the same thing as saying that members of the team were not allowed opinions or contributions.
If I am team leader, I expect everyone on the team to participate in planning, and I want to hear any and all thoughts, especially those counter to what I am thinking.
From what I've heard about how the WKPP planned dives, this is exactly what they would expect, too. If you were on the team, you contributed your knowledge and talents. If you didn't, there's no reason for you to be there.
In short, I don't see anything you posted above that is directly contradictory to how Parker or the WKPP ran things. Once you proved you had the ability, motivation and team ethic, once you were invited, and once you became a member of the team, your thoughts and experiences would be welcome, and your contributions commensurate with your experience would be part of the planning of the dive.
