I guess.... one sometimes have to learn to agree to disagree.
Whenever my partner and I have certain disagreement, he would ended up suggesting, "let's agree to disagree." instead of debating till the cows come home or worse, ended up with sore ego (from both ends, since I am quite a hard person myself).
I am sorry to hear that one topic could flair off such an unnecessary waste of VP. (to my point of view)
