If you disagree on a material issue, it is your responsibility to explain why you disagree, ideally in both discussion and in writing. The back and forth of discussion can clarify the different views, and concise writing of the core issues helps people reflect on what is the wise course, as well as making it easy to share views widely. The informed captain on that decision has the responsibility to welcome, understand, and consider your opinions, but may not agree. Once the captain makes a decision, we expect everyone to help make it as successful as possible. Later, if significant new information becomes available, it is fine to ask the captain to revisit the topic. Silent disagreement is unacceptable and unproductive.
