But this has less to do with Martial Arts and more to do with the nature of fans and spectators sports.
A baseball fan will argue that it's "better" than cricket. American rules football is "better" than rugby. Or vice versa. It really just depends upon what sport the fan enjoys watching. Baseball in America has the same thing. The more you understand the strategies and subtleties of the sport, the more enjoyable it is to watch. So, you'll have guys who are passionate about the sport, who watch every pitch and who can talk like they're the general manager of the team, but who may or may not have ever played the game. Fantasy leagues have only exacerbated the situation.
This isn't a mystery, folks. It's human nature. The people who watch the sports are the ONLY reason people are payed to play the sports. MMA is most certainly included in this.
