Because they are the most pointless ever invented form of entertainment for the unintelligent and there really is no point to any of these I don't know what to call them they aren't sports. They are just so disgusting to me and unintelligent. I even used to take martial arts but I quit because of the stupid fans signing up for a few classes just so they could fight without any purpose. It's honestly the most annoying thing in the world to me.
