By 'unwarranted', I am saying your general trust for humanity is, in Bunyip's case, demonstrably 'unwarranted' by his inhuman attitudes towards those who voice disagreement with him. I see Bunyip as a horse needing to be broken.
I have been reading your arguments and find them so destructive to Bunyip's that he is unable to address them. However, if you have read the thread, you'll see that you are not the first person here to place Bunyip in such an argumentatively supine position. Upon being mounted, it is the first instinct of some unwilling mates to "buck". It is, more or less, an intellectual version of "bucking" the various fallacies he must perpetuate in his mind to avoid submission to the superior argument.
Bunyip is, as Legion put it, 'cheating at solitaire'. He is gleefully celebrating victory while the rest of us look on puzzled as he celebrates, as Mister Emu put it, 'intentionally stunting [him]self intellectually'.
It is no use arguing with one who can think down is up and left is right. So all of us just keep on mounting him over and over again with superior arguments until he is a good trained little mare.
