Are other fans jealous of our success?

Has anyone else had to deal with this?  I've spoken to many baseball fans about the A's recent success, and the responses I always get are:

"Oh they won't catch Anaheim"  


"Oh they still won't win the wildcard"


"They're eventually gonna have to come back to earth"


"They're just overachieving right now.  They're not really that good"

And as I hear this more and more, and as I watch baseball tonight begrudgingly give more time to A's highlights since we've blasted our way into the lead for the wildcard, I sense that people really don't want us to succeed.  Maybe it's the fact that we don't spend 200 million a year on our  players.  Maybe it's the fact that we don't bunt, steal or do any other "small ball" things, yet we continue to win.  Maybe it's the fact that we have the best young pitching staff in baseball, again.  Maybe it's the fact that Billy Beane has basically made a lot of GMs look foolish with some of the trades he's made.  But for some reason, it seems to me that the only people who want the A's to do well are A's fans.  Can anyone explain this to me, because it baffles me.  Our team is young and inexperienced all over the diamond, but they are exciting to watch and they play hard, without a lot of complaining or grandstanding.  And we've been winning like crazy.  So tell me, what is not to like about our beloved Oakland A's?
