I'm fucking sick of this capitalist society...

I think it's a form of American nationalism. Their team is the imperial "capitalist" team. Americans just associate with it a lot now, but it's dying off the further we get from the Cold War, since there isn't as much sustaining the hard line between "our enemies are socialists, and we are capitalists!".

Gringos developed the only successful system on planet earth. Somebody like you needs socialism to make anything in the world so I can understand why you desire it but I'm afraid the world doesn't cater to the weak and stupid.
