To me bad faith is also just lying. You lie about your motives and intentions. You lie about the other's sides motives and intentions. Bad faith actors also prop up a lot of straw men in order to tear them down, but disengage or put words in the mouth of direct opponents. They make concrete statements, then back away and act like they never said if called out for it, or can't back up their assumption with evidence.

Bad faith arguments are more about scoring points or making that person feel better. It's never about the actual policy. So it allows the bad faith actor freedom to say whatever they want, as long as they come out ahead.
