I'd think this proves my point: we're having a debate, without an obvious "victor" about whether or not a mission to focus on sandwiches without distraction would lead to fighting segregation.

You say that someone could justify that. I'm saying they could also do the opposite. My point is that a "mission-oriented" code of conduct if you will allows the people who set the mission (read: leadership) to set the ethics too.

Fighting segregation can be part of the mission, or not. But if it isn't, you can't work on it.
