Strange country
The US, or rather its citizens, makes for a strange country. On one hand, it's perfectly fine, indeed actively encouraged, to carry a gun and shoot people. On the other hand, exposing a bare nipple (remember the superbowl?) is a crime so heinous that only the most severe punishments are appropriate.
I was watching the news here in the UK the other night and they were talking about Barack Obama and the very recent surge in (basically) anti-Obama feeling being stirred-up some self-styled group called the Tea Party, or some such thing. The thing I found interesting was the number of people that believed Obama was (a) not actually an American, and (b) was a muslim. Even though they have been presented with his birth certificate and Mr. Obama swears he's not a muslim, they still don't believe him. What is the point of recounting this? Well, I think it is a symptom of the American psyche. Are they just plain bloody stupid? Or mentally and socially backward? Plain and simple racist, maybe? A bit of all three? They claim there is no racist element to their protests. Personally, I find this very difficult to believe; if it looks like a duck... But then I'm sure some of them are are not racist (just pretend for now, right?); in that case, just how stupid and engrained in your own little bubble of backward social upbringing do you need to be to carry on the argument?
I think it is this exact same backward/arrogant/stupid attitude that leads a whole nation to protest at a nipple being displayed on telly (even when it's covered up!). I mean, can you imagine? An actual nipple? The shame of it!! Burn the heretic!!
But this attitude (which seems endemic in the American society) couldn't contrast more than it does when you look at the fact that the US is the biggest porn producer in the world. Maybe it really is just a screwed up country with bizarrely screwed-up values that really don't make any sense.
When you consider the psychology of this nation, it is no wonder at all that its contradictory and often nonsensical value are exported via the internet. It is inevitable. Facebook can't really allow the rest of the world to post up pictures of nipples, but not allow good honest Americans to do the same, can it? It would have its (American) offices fire-bombed in something reminiscent of abortion clinic. Abortion; as it happens, another very screwed-up argument that gets WAY out of hand in the US - I mean, at least let the little buggers grow up so they can hold a gun and shoot back! Give 'em a fighting chance, you know.
As a side-note, you point about the UK suffering because we speak (notionally) the same language. There is definitely something in this. Americanisms infiltrate our media all the time; it's getting to the point where Radio 1 sounds like its broadcasting from some Bronx ghetto or something. Or maybe I'm just getting old :-) Actually, no - it's not that. Yes, I AM getting old, but that's no excuse to bastardise our language with such nonsense. And have you ever tried selecting the "English" (rather than "American") language option in your computer operating system or software of choice? You're doing very well indeed if you can find it; it seems that us Brits should be perfectly happy with American "English". Apparently, we don't need our own language at all.
