Well, he IS right in a sense. WWE is character driven, storyline driven, and the direction and fate of everyone involved is guided by the powers that be behind the camera, just like with any other fictional television show. No one is actually going out there and winning or losing a match for real. Undertaker didn't actually have an undefeated streak at Wrestlemania. John Cena isn't actually overcoming the odds. Hulk Hogan didn't actually beat Andre The Giant. Etc., etc. That's what completely distinguishes it from things like boxing, mixed-martial arts, basketball, baseball, football, soccer, amateur wrestling, tennis, racing, and the other hundreds/thousands of sports in the world. Competing for spots or pushes backstage doesn't count, as actors and actresses compete for roles in movies and television too, yet I can't recall the last time someone categorized acting as a sport.
To be fair, WWE do call it Sports-Entertainment for a reason, but it will always be far closer to pure entertainment like any other show because of the predetermined nature of the business and the fact that there's no legitimate competition going on in the ring. Matches are fixed, guys win or lose depending on how it works within the context of the storyline, guys get pushed to the top because of business reasons (i.e. who will draw the most money) and not because of how gifted they are athletically, etc.
Anyway, this topic is kinda going off the rails at this point.
