In an example from his book The Treason of the BBC, Mr Parsons writes:
"For many years there has been a lot of opposition to open discussion of the perennial problems of balancing numbers and resources against each other to provide a decent quality of life for all. Nonetheless, for some years the media—including the BBC—did from time to time provide a platform for quite searching articles and programs on the topic.
"...[Elsewhere] I have labelled this major national turnaround 'The Great Sex-Population Volte Face,' drawing attention to the complete reversal of our original attitudes two or three decades back.
"The previous mores permitted limited openness on population coupled with very tight restrictions on sexual matters, whereas the present mores enforce a near-total ban on population coupled with an almost complete absence of restrictions on bad language, pornography, and sex in general."
That is, of course, putting it mildly.
