I don't think it's personal. He's the same as your dad was in the 60's, trying to protect his childrens' childhood for as long as he can. I don't blame him as children seem to be pushed into adulthood nowadays before they've had time to play.
In the 60's, UK and USA, 16 was the age that one was allowed to make a number of personal choices. As "canarieslover" has said, in some States of the USA, one reaches Majority at 13.
In the UK, it was 12 for many centuries.
In most Countries the age of Majority, ability to Vote, Fight, have sex, get married, drive a car, drink alcohol, is an Economic decision made by the Ruling Elite, and has little to do with anything. In some States the local Spiritual Leaders try to get their oar in as well as the Temporal Authorities. But even in this day and age, it varies throughout an 8 year spread and most everyone either agrees, or disagrees, with their local set-up depending on their needs and desires at the time.
"lily allen, i think, yould argue that she doesnt make music for 6 year olds." Is the nail hit square on the head.
I personally think her lyrical interpretation of modern society, is as avant guard as Ray Davies singing about the swinging '60s or Lou Reed singing about the seedy New York scene of the same period... she's a lyrical genius.
in fact, she pretty much said as much on an episode of "...Buzzcocks". Another panelist commented how there could be a "clean" version of her album for her daughter and allen said, "well i didnt make it for her".
tho i appreciate its difficult, but what can you do save for implement a certification system as with films, and i wouldnt approve of that.
