It is, but that's how a lot of people feel. No one likes to back a loser. Especially if you're spending hard earned money to go see games live. 

And I didn't mean it as in that's how I personally feel. That was just an example of how I think many people do feel =)

You are actually probably correct.  It is a very well thought out post and probably holds a lot of truth to it.
