Well, a simpler example: Imagine me writing as someone using PNG format. For me using English is like being forced to convert to JPEG format, you lost information in the process. Or maybe you are simply being sarcastic in a very stupid and arrogant way as is common among north-americans, who knows.
Actually, I'm Australian, although I did live in America for a while.
American English/Aussie English both have their differences to the Queens english (And even though us Aussies generally could care less about the queen, all she is to us is a public holiday once a year, really) Us Aussies still know we don't speak "Proper" English, and we're OK with that.
It's strange to me however that I find Australians seem to have very little problem with accents and "dialects" - american, english, irish, south american, whatever, it's all "english" enough that we don't need subtitles or translations 99% of the time.
It was weird as hell in America, however, how often they subtitle other english speakers on TV.
In any case, I've also lived in Finland, where while almost everyone under the age of, well, about 40 now I guess, can converse in english, however it's usually a bit of a struggle, as Suomi (Finnish) is so very different from English (At the same time many many Finns have better english than I do).
Most Finns speak Finnish, Swedish and English, and many add Russian, German, and other languages.
I've found in general, people who speak multiple languages (who speak them well, so this doesn't include me) tend to have an advantage when communicating in any of those languages.
English is like transferring a png into an open source image format that people can hack to do whatever they want, transparency, localised scaling, whatever you think of, just hack it in, borrow some png code, some SVG concepts, and plug them in. English is flexible. Most other languages are far more rigid, which makes them easier to learn completely, but will hit the limits of that language. English speakers hit limits, and they just borrow/co-opt something from a language that has it, and make it work. English is more of a sandpit, and yeah, dig around you'll find plenty of crap in it, but it works.
p.s. sarcasm is a great tool, but explicitly identifying it as such would take the fun out of it.
