Being REALLY open minded means being really open minded not just appearing to be or just successfully "dealing with" other supposedly close minded people.
I like the "you COULD be right" line if you really mean it and are interested in truly understanding the other's position/opinion so that you might change your own. I don't care as much for the "you're right" line, since it seems more of an attempt to defuse situations and shut people down, than it does a recognition that they really are right from YOUR OWN perspective too (otherwise you're still being close minded.) This could also be true of the "you could be right line." You should be striving to clarify and improve your mind, not just looking for gimmicks.
Personally, I've changed (and sometimes changed back) my political, religious, spiritual, social and physical paradigms.
