How many right wingers do you know who are interested in introducing a bill of rights where those rights are not going to be determined by the people in a referendum but by the courts or a parliamentary majority? All these movements want to achieve is to lock in a left winger's view of the world as the only viable negotiating position. look at the Bill of Rights in Victoria, Australia- far from guaranteeing that most fundamental right, freedom of religion, it has in fact been used to over ride religious objections to abortions and was going to be used to override hiring practices in religious schools.
