No, it's not about criticising, but turning every post into a discussion about the US. There's a lot of Americans in this place, and they don't know much about the rest of the world, so they filter everything through their experience.

"La culture, c'est comme la confiture. Moins on on a, plus on l'étale" — Knowledge is like jam, the least you have, the more you spread it.

{Latin Americans, Europeans, Africans, etc...} don't know much about the rest of the world, either. But it seems that only people from the United States are criticized on this website for not knowing a whole lot about how things go in different continents.

The cliché at hand is more about the quality of Italian food in Italy than about any cuisine in the USA. Food-wise, the US is actually doing pretty well among Western countries. I'm not going to name the countries at the bottom of the list to be respectful, but they mostly don't dispute it.

If you want, coin the name. The fact is that the probability of any topic being mentioned in a discussion approaches one as the length of the discussion approaches infinity. It should have been called Godwin's Tautology. :)
