A most fantabulous question! There is a solution to your problem. The trick is to stick to your original (wrong) point of view, which irritates the other person to no end, usually leading them to babble on about the hopelessness of the argument. Herein lies the oppurtunity to take victory, as during this time people often say stupid things out of frustration - so you pick up on their lack of logic and the inconsistency in their argument and take it apart! Always works like a charm for me - I NEVER lose an argument!
