When working with editorial boards you need to act in such a way that they will respect you and not dislike you.

I think the best thing to do when you're dealing with editorial boards is to be as open and honest with them as you possibly can. Even though they might not agree with you, tell them that you understand that and that you also understand that they have a job to do and you're going to continue to make it as easy as possible for them to work with you. I can promise you, if you tell an editorial board that, they are going to have a great deal of respect for you, even though they might not necessarily agree with your position.
