"Attitudes to sex and death in the USA seem a little strange sometimes - Mainstream US film classification seems to regard death and violence as OK, but sex is not to be tolerated"

Where do you get this crap? Who thinks for you???

You seem to confuse the FCC and the MPAA for the USA.   A handful of people who make supposed "rules" are not the voice of Americans anymore than Queen Lizzie speaks for the average Brit.

The USA loves sex just as much and probably much more than most countries that still seem to be suffering from Victorian ideals.

It also seems that every erotic novel that came out of England dealt with bondage or young schoolgirls. What is up with that? Should we come away with an impression that is the UK view of sex - equating it with violence? You cannot judge a culture solely by the media.
