An example of what? It's an invalid comparison, that's all there is to it.
And lots of people may rationally be aware of the fact that their team winning something doesn't change their life, but they emotionally are so tied up in it that they feel like it would. So many fans consider their teams winning things the absolute highlights of their lives. They feverishly hope, dream etc. about it. It can absolutely consume them. I don't even want to know how many seriously meant prayers were said in Argentina on Sunday to ask for victory. People weep when they lose, they start fight with others, they weep when they win too and they may hug total strangers. It's not all that logical, and it's also obvious that it's not some 'diversion' where 20 minutes afterwards they dust themselves off and go back to normal life.
I'm not that invested now and haven't been for years, but when I was younger? Sure, I was obsessed with it. If you don't understand any of that, then I don't know how you can call yourself a fan to be honest. More like a 'casual observer' which to be honest given how bent out of shape you get by so many of the arguments on here doesn't really have the ring of truth.
