If people's points have all been made, but the argument isn't going anywhere, then there is nothing wrong with agreeing to end the argument. You can't always end with agreement, but you can just stop arguing. It doesn't mean you're weak or that you're wrong. It just means further debate is pointless and thus a waste of time and energy.

Sometimes it can be more difficult to decide to stop arguing than it is to continue the argument!
I'd agree with that... if it were a claim. :)
