Fair Weather Fans~Ugly American Fans

I've noticed that they're many times the same people. examples:

• an old "friend" of mine who liked the Cowboys, Islanders, Lakers when they were good, dumped them all when they were bad. favorite baseball team, surprise, the Yankees. said the Olympics didn't mean much, put down soccer all the time
• 
  
• another someone close to me at times, a gym teacher and coach no less, who rips everyone else for being fake fans, yet his favorite golfers are Jack Nicklaus and Tiger Woods, favorite baseball team the Yankees, dumped the Cowboys, Rangers, Knicks, Giants when they were bad. also thinks soccer is a non sport
• the American fans that put down soccer fans for their hooliganism, rioting etc. guess they see the bad in other nations and only the good in ours (right wing methodology?): see the riots after the Chicago Bull victories, Laker victories, Michigan State sports, to name just a few

by the way, the American fans that put down soccer, do they realize that baseball is the "national pastime"? a game where you barely run, you rarely jump, not really a contact sport, scoring is often low, most of the action is between 2 grown men having a catch?

for the record, i actually enjoy all the above mentioned sports, honest
