We know best

In a move that is bound to be controversial if adopted, a Tory policy group is proposing a tax allowance for married couples, which will be worth around £20 a week. It is one of some 200 policies proposed by Duncan Smith's "Breakdown Britain" report, which aims to mend Britain's "broken society".

Whether our society is "broken", and whether marriage is so valuable that it should once again be favoured by our taxation system are matters that will no doubt cause fierce debate. What I don't like is this arrogant "we know best" attitude, whereby one group of society tries to impose its values upon the rest. There are many ways in which people live their lives, and those ways are equally valid so long as they do not affect and are not imposed upon others, whether by force or coercion.
