The designation, whether granted or self imposed, of "true" or "real" wrestling fan is completely meaningless to anyone other than the person using it. People will completely define in their own terms what it means to be a "true" wrestling fan for one reason only: because it is a subjective measure and that is how subjective measures work.
I honestly don't think this article makes any practical point. It in fact makes the same argument it is arguing against. It is saying that internet fans cannot define what a "true" or "real" wrestling fan is but the pure fact is that they can because it's a subjective measure. But, again, that definition is meaningless to anyone other than the person describing it.
I don't think wrestling having a "fractured" fan base is actually a bad thing. The entire basis of wrestling is conflict. Wrestling needs conflict in order to exist. The wrestlers fighting is conflict. The reasons the wrestlers fight is conflict. Wrestling fans, like any other sports fans, have conflict with each other. We disagree with our friends as we watch the shows. We disagree with fans when we are at the arenas. We DEFINITELY disagree with each other when we talk about wrestling on the internet. The so called "fractured" fan base is one of the things that drives the industry.
Those arguments on YouTube, those arguments on the internet and those very arguments on WWEForums may fuel the divide of a fractured fan base, BUT they drive the lifeblood of this industry. Our disagreements about Roman Reigns make what happens with Roman Reigns more interesting. Those people who HATE John Cena fans as well as those John Cena fans who are pissed and confused as to why he is so hated... those conflicts NEED to exist. Those fans who call each other names and insult other fans and criticize whether they are "real" wrestling fans add fire to a business based completely on conflict. They are necessary for this business to thrive.
If we put aside our conflicts on the internet, including which of us are "true" or "real" fans, then wrestling's presence on the internet, and likely wrestling itself, would be pretty damn boring in my opinion.
