Ok, although having had a TV during the 90s, and subsequently I have never watched an episode of ‘Friends’, I understand what you are describing to be what I term ‘the lowest common denominator’ , although a mathematical term it is something which is inherent in democracy, and anything else which is aimed ‘at the masses’. By which I mean to say that whatever ‘it’ is, it has to be understood by everyone, and thus to ensure this it has to be ‘dumbed down’, to the level of the lowest common denominator. Consequently rather than the fall of Western Civilisation what you describe is a component part of that civilisation, as it is based on democracy. (You only have to look at the current US statements by would be Presidential nominees for more than sufficient evidence of this.)
But why, oh why, does one have to read a ‘fucking’ book. Although if I could find one capable of sexual intercourse then, yes , I would be tempted to read it. However, such a thing seems rare, I only read 2 to 3 books a week and have yet to come across such a rarity.
It used to be that the use of expletives was to ensure shock or to stamp importance on a matter, but now it seems unavoidable in almost every phrase, (back to lowest common denominator??). Please do not think I am a prude or an idealist (30 years as a Police Officer surely make either option impossible), but as language is the main medium of communication then surely greater care ought to be used with the words presented to an audience.
