OK, so tell me specifically, what does a sports fan, at the end of the season (or game for that matter), have to show for it, regardless of wether “their” team had won or lost?
I don’t know. Different people get different things. What do you get out of whatever activities you participate in? I’ll bet what you get out of one or more of them are things I couldn’t care less about — does that mean you should abandon those activities because *I* don’t value what you get out of it?
They don’t have to get anything out of it. They can do it for any reason or no reason at all. Why do you have a problem with that?
