The document we have sure ain't broken, so why change it? THERE are two ways of understanding disagreement on important public issues. One way is to assume your own view is the result of some sort of pipeline to God, indisputably good in other words, and so all those who disagree with you are either dumb, malevolent or in need of some re-education. The other way is simply to recognise that a lot of smart, nice, well-informed people simply disagree on all sorts of important issues ranging from euthanasia to how to deal with those trying (dare one say illegally?) to come to this country by boat, over to labour relations, on to whether to amend our Constitution, and more.
