American folly

It's not just in relation to children (though much stronger where under 18s are concerned). The USA has this bizarre fixation on sex, where any sexual content, including something innocuous like naked breasts, gets big flashy labels to protect the 'innocent' from seeing such terrible things... Yet murder and graphic violence are okay as long as you can't see too much blood.

And as with all American culture, it is spreading over the globe like a plague.
