I think that demonstrates that the meaning of "bad-faith" is, well, in bad faith. A correct definition of "bad faith" makes it a question of the speaker's state of mind. Not only can the speaker always judge this for himself, but he is the only one who can judge it. The only way a speaker could fail to realize his argument is in bad faith is if that is a question not of his own state of mind but of the listener's opinion.
