What I find stupid is the claim that it was patriotic when they had everyone waving foreign flags at the end and a football saying "We are all America" on it.

Like, nobody cares that the continent you live on happens to share its name with our country. Living in South America doesn't make you American like us. The fact that Latin Americans try to make that claim really comes across as an inferiority complex, like they're ashamed of their own countries and desperately wish they were Americans.
