Ah. It sounds like we have different interpretations of what SarahC meant by out-argued.

I don't believe a clever debater can long-term convince me of the falsehood of something I believe and feel strongly about (sadly, even if it's true), although they might induce me to go along temporarily.

This is, incidentally, not to say that I can't be caught up in cultishness, merely to say that clever arguments are sufficient (or, sadly, necessary) to do it. (ETA: er... I meant, of course, "are not sufficient," which was perhaps clear)
