You guys are worried about "automobile"?
You gotta wonder about any form of English that wilfully refers to man as a c#nt.
A great word. A king (queen?) among words. As is twat, twat is more versatile but not as offensive. You can't go around using the etymology of swear words to launch an attack with out taking some collateral damage yourself. Look at 'fuck', for example. Doesn't really make any sense either, does it.
It's interesting how much the dialects change in the UK, you can trace the changes across and up and down the country. No idea why American dialects don't differ as much, at a guess I'd say it's to do with the shorter history and lack of multiple invading forces over the years.
Anyway I posit to you that you're now engaging in the same kind of antics that you say have riled you so much, it's all a bit silly isn't it - no one chooses the language they speak or how it has developed. Are your colleagues likely to respond to that kinda thing?
Also I suspect you're right about the anti-America thing. I've met people like that, can be a bit boring to be honest - there're lots of them back home.
Also also, it's an article by one writer for The Economist. Just sayin'.
