Imagine a cartoon (I wish I could draw one) in which a school teacher is explaining to a class of children the reasons for not smoking, while in the world outside virtually everyone is doing just that: on the streets, in their homes, on the TV, in films, on advertising hoardings etc. etc. Not so long ago that was the reality.

It still is reality in respect to sexual behaviour. If the Muslim burqa is the expression of one extreme related to sexual behavioural, then what has happened in the West over the past 40 years is the expression of the other extreme.

The trouble is, we have gradually become so completely immersed in this moral corruption that it is seen as being perfectly "normal", so we barely register it.

The sexual content of TV, films, newspapers, magazines etc. is phenomenal. We all know why, of course: man's natural fascination with sex, combined with the fact that it "sells ".

How can adults, who have been so thoroughly corrupted and have so little idea of the meaning and importance of sex themselves presume to teach children what it is about and how to behave?! It is like an obese chain-smoker and alcoholic giving health education!

Sexual behaviour (including kissing) is (or certainly should be) an extremely intimate and private matter, which, except under exceptional circumstances, should not be put on show at all. And where it is, the decent thing to do (in most circumstances) is to look away.

Having said that, you will no doubt think that I am the one who is being extreme; but that, I suggest, is because, you, like most people, have also been corrupted (I've been corrupted too, of course; it is just that in contrast to many people, I can see it).

However, the central problem is not so much sexual as pecuniary. We are in the grip of an economy (rooted in man's primitive animal nature) which exploits everything - our whole planet, mineral, vegetable, animal, even our fellow man and our own animal nature (particularly our sexuality) - for the sake of making money. The "sexulisation" of society is being driven by rampant "commercialism ".

Even worse than corrupting our sexual behaviour, rampant commercialism is causing us to plunder our planet's natural resources (particularly fossil fuels), leading us inexorably towards climatic, environmental, economic and social catastrophe. The corruption of our sexual behaviour seems hardly worth worrying about when the threat we are facing (but not facing up to) is possible extinction.

On the other hand, recognising the primarily commercial cause of sexual corruption might help us face up to the underlying problem of our addiction to and dependency on an economy rooted in our "more animal than human nature".
