Is there a legal or moral basis of the government's draft bill on religious freedom? I reread the Universal Declaration on Human Rights (a reasonable place to start as Australia does not have a bill of rights). My reading of it is that human rights apply to persons, not organisations or governments. The declaration requires governments to protect and maintain the rights of individuals. There is no mention of governments legislating to allow selected organisations to discriminate against others.
