The problem is that if someone is acting in bad faith, it is almost impossible to answer every single challenge that a truly bad faith actor might bring up. And even if you answer 99 challenges correctly, but you instead make a single small mistake, or you mispeak, or the other person intentionally misinterprets what you are saying, then the bad faith actor can declare victory and "win" the debate, because of a single, irrelevant, or minuscule mistake. If someone is not acting in bad faith, it is almost impossible to not lose to them.
