Mulan:
I guess you can say that it is a sign of maturity to agree to disagree. But when the subject is very important, sometimes you must go the extra mile to "fight" for what you believe.
Case in point: My Ashi was over this past weekend. We had a heated discussion about something that I won't go into on this board, but, since we are both very "vocal" we like to try to prove our points in a very loud, but controlled way. Well, we didn't end up agreeing, but that's still OK. People can have different opinions on things, as long as they don't take out an eye in the process. I still have both of my eyes, and last time I looked, Ashi had both of his.
