Indeed. Good advice.
I was tempted to refute one of the "critics" yesterday, but thought, what would be the point? If you start with your premise that everything is a lie, then that's not argumentation, since its not defensible, particularly when you impugn the source, which in this case is two different people. You can infer anything, while not having to prove nor defend a single point. One of the posters I dug up old comments of that indicate motive to flip, as they were clearly their words. That makes two who have stated thusly, one who makes little attempt to hide it.
