Guess I can live with their existence, but man do I get annoyed at contantly being asked if I "Caught such and such a reality show last night" or "How about them -insert random sports team here-! Pretty great game wasn't it? What did you think when so and so made that such and such and won them the game?" Usually I have to say something along the lines of, "Yeah, that was really something." to appease them, everytime I say, "I dunno, I didn't watch it." they look at me like I just told them I enjoy humping dogs.
See, I love sports, especially basketball, but I sympathize with the idea that a lot of sports fans are not only morons, but that they enjoy being morons. I love watching sports because it's a treat watching the best players in the world doing things I can understand. If they televised world-class physicists doing their thing, I'd respect it but I couldn't follow it in the least.
There are plenty of intelligent sports fans out there. Read Bill James for the perspective of a truly intelligent fan.
