While the majority of England's population is not what is depicted in the media as "tea-drinking-bloody-saying limeys", most of it's internet population as self centered bigots, who openly boast about the "greatness" of their country, and putting down America because we created our own culture after gaining independence, and we don't constantly praise England. See highest voted entries for verification.
Even as England complains about how Americans "all think we talk funny and are all posh and drink tea" they make equally brash generalizations about Americans, about how all Americans are "fat, disgusting, crude and play fake sports like American football" A lot of English people tend to use what happened hundreds of years ago as the main point of their arguments, thinking that their generation of people are the ones that "freed" America, when the majority of the English aren't even related to strong political powers during the 1700's, nor was America freed by English, but instead the war was won by America that earned America's freedom.
Some English individuals are incapable of accepting other people's cultures, since it is not their own, and therefore it is wrong.
America - "Why?"
England - "Because it's not like our football!"
America - "....."
England - "You should stop playing baseball! Why is it called the world series when it's only played in America?!"
America" One, just because it's not massively popular ni your country doesn't mean others should stop playing it, two, it's called the world Series because a large quantity of players who play in American Baseball teams are from around the world, and multiple countries play in the world series, namely Canada and Mexico. People do play baseball in England too, you know."
England - "Your culture is stupid, you call lager beer, which is wrong!"
America - "We're sorry that we have developed a different culture now, and part of that includes different words for different things."
England - "Well... your culture is stupid! And all American's are fat and disgusting!"
America "wow... Yes, around two thirds of American adults are considered over-weight, so are half of English people, with that number steadily rising."
England - "....... your still dumb!"
America - "The literacy rate for both America and England is 99%."
