Simply providing a counter-argument to an argument, whether it's 'pessimistic' or not, does not constitute a fallacy of any kind. The author's chief complaint seems to be that people have the temerity to counter his arguments. You can't call an argument a fallacy based solely on your perception of the motivation of its proponents; a true fallacy can be proved simply by examining the argument itself.
