Nah, it just proves that American pronunciation is the easier, more natural and thus correct version, while RP Brit pronunciation is contrived, unnatural and more difficult, thus incorrect... /grin
Tell that to my wife. We have occasional pronunciation or mispronunciation battles if you prefer. She'll sneer at some of my American pronunciations, and I get back by asking who put all those extra consonants and vowels in words that don't need them. Nobody really wins.
