No, I think that his point is that the opinion of a competitive gamer is hard to respect, mainly because they completely miss the point of a game [http://tvtropes.org/pmwiki/pmwiki.php/Main/StopHavingFunGuys].
Stop Having Fun Guys are a very very specific breed of competitive players, just as scrubs are a very specific breed of pubbers. Categorizing either group as representing their entire respective populations is just silly. For every douche of a competitive player one could list, another could just as easily list as many (if not considerably more) clueless pubbers. There's nothing inherently wrong with playing competitively, just like there's nothing inherently wrong with playing casually, similarly to how sports games and board games like Chess/Go can be enjoyed both very casually and extremely competitively.
In the end you should just treat people as individuals. The whole "hah, like we'll listen to competitive players" comes off as much, much more closed-minded, condescending, and douchy than 90% of the competitive players I know. The loudmouthed ones don't represent all of us.
