Feh. American English
is real English, the English that real people spoke. Britain's "received pronunciation" is the result of 19th century Francophiles butchering their own language, then, because those Otaku happened to be the rich nobility in Britain, passing laws forcing the common people, who up to that point
were speaking real English, to speak pidgin Frenchified English instead, a practice that continues to this day.
British "English" is the 19th century version of LOLcat speak, enshrined into their law as their country's official language.
