Sometimes the right thing to do is to agree to disagree, or just disengage. And as we can't all have the last word and it would be chaos if we all tried, the path of greater virtue is sometimes to just recognise when you've made your point and stop arguing even if someone else still disagrees.
I'm just chucking this in there as I'm not going to be around for the next few hours, and I think it might be something worth bearing in mind if anyone is tempted to continue some strands of this discussion.
