"I really don't mind debate, as long as the exchange is amicable and respectful. Once is becomes clear that ones premises are not being considered or debated, but that name-calling and irrational statements begin, the debate is no longer a debate but a brawl.

...And, it is irrational to expect to "win" every debate. That doesn't mean your premise has been disproved, but that you have failed to convince the other party. As I often say, " a man convinced against his will is of the same opinion still." (I don't know the author of that quote.)"
