Getting grown men (and women) to cheer for someone when they know it´s just theatre (they do know it´s just theatre right?). Yeah, i would say that is the most idiotic gimmick ever. If i go see Romeo & Juliet in a theatre i think i´m gonna start yelling "NO, ROMEO, DON´T DO IT, SHE´S NOT REALLY DEAD!!!!" on the top of my lungs. I bet people won´t think i´m an idiot at all after that. I can respect the athletic ability of the performers. It´s the crowd in the arena that make the whole thing completely ridiculous, they obviously don´t have a whole lot going on in the brain department.
You do know what entertainment is right? Well wrestling entertains a vast majority of people around the world and yes they know it's staged. Wrestling is a throwback to the traveling carnival days. It's all an illusion. Just because you're not entertained by it and others are doesn't mean that they are stupid. That's like when people are talking about their favorite horror movie and saying why are people always talking about body count? Don't they realize that the people are actors and they are not dead?
