Perhaps the most important thing about debate is audience. Many people look at debate from a one-on-one perspective -- 'can I convince so-and-so to change', but much debate isn't about convincing your opponent, it's about convincing people listening or reading along. You're talking to them. Frankly, fundamental disagreement isn't likely to be resolved via debate. People change fundamental beliefs mostly by convincing themselves (and listening to others debate).
