In all seriousness, i think MMA moreso than ANY other sport has a huge following of fans who have never actually participated in it. Most other fans of sports have at least dabbled in the sport, rec leagues, hs, etc... most MMA fans consider themselves an expert because they once sucker punched their cousin while watching MMA on tv.
Not saying someone has to have been a professional to be knowledgeable about the sport, but in most cases it certainly helps to understand what they are really trying to do vs. what joe rogan has told you they are trying to do.
