Of course, some people may choose not to lie, for religious, ethical and other reasons, and that's perfectly OK too - nobody is suggesting that lying be made compulsory. But for those who choose not to lie to try to impose their morality on others is completely unacceptable in a democratic secular society.
For the majority, lying is an enjoyable activity, and the repressions of a few fanatics should not make the rest of us feel guilty about it.
I'm thinking of organising Lying Education for primary schools, Lie with Pride marches, and a complete ban on any negative stories in the media about lying (given how many journalists lie, surely that is the ultimate hypocrisy.) We will present the public with a range of really tough choices and hard cases to help to educate them about this (not all of which need be true of course, as we lie with pride...)
