Why should religions get tax-free status for money raised and spent for proselytising? Credit:Michele Mossop For a start, religions get a free kick under the Marriage Act. If you are a minister of religion of a recognised denomination, you are automatically entitled to be registered as a marriage celebrant. Civil celebrants, on the other hand, must meet other requirements, such as knowledge of marriage law, an ability to advise couples of relationship services, and be of good character and standing. With respect to marriage, surely we should have the same rules for everyone. Wasn't that demonstrated on Wednesday? Perhaps we should start a campaign to take religion out of marriage laws altogether. At law, everyone should marry before a competent civil official. If religious people feel that that would not be a real marriage, they can go off afterwards and do a religious ceremony. Further, why does the parliamentary session at which these questions are debated begin with a Christian prayer? If parliamentarians mirrored the community, about a quarter would be atheists and most of the rest would not be observant Christians.

There's more. Why should religions get tax-free status for money raised and spent for proselytising their religion, as well as for raising money through commercial enterprises, even if there are grounds for tax breaks on charitable work? And on the charitable, medical and educational side, why should religious institutions escape ordinary anti-discrimination employment laws, especially when they get very large amounts of public money for this and are significant employers? And why have we wasted $300 million over the past half decade on the schools chaplaincy program, under which educationally untrained religious operatives spout uneducational, unscientific twaddle to schoolchildren when we are crying out for money and training to teach science, maths, English and history? The concessions given to religions in Australia are already too wide without giving them any more. So if conservatives start seeking new rules allowing commercial enterprises to discriminate against same-sex couples when providing goods and services, they should be on notice that existing concessions for religion should come under scrutiny and, unless they can be justified, they should be removed.

Freedom of religion is like freedom of speech, freedom of assembly, freedom from search and seizure, equality before the law and property rights. It is not absolute and needs to be balanced against other rights and interests. Freedom of assembly does not permit you to block peak-hour traffic. Freedom of speech does not permit you to yell fire in a theatre or trash reputations. Freedom of religion does not permit you to have four wives, refuse education to your female children, smoke marijuana, assault your spouse or beat your child. Nor should it let you discriminate in employment. Same-sex marriage is part of a historic continuum of increasing respect for human rights and equality: an end to slavery; increasing voting rights; respect for women's property and voting rights; anti-discrimination laws. There should be no going back, but history is replete with examples of regression to authoritarianism and discrimination. We must guard against that here. Of course, there never should have been a plebiscite, because equality before the law is an inalienable right, not something that can be granted or taken away upon ephemeral democratic will. A lesson from the plebiscite is that these inalienable rights should be enshrined in the constitution so they can no longer be the plaything of the political process. A further lesson from such a huge turnout and decisive win by "yes", despite Australia's susceptibility to scare campaigns, is that Australians are interested in social progress. Most of Australia's successful referendums and plebiscites were on socially progressive causes: two against conscription in 1917; social security in 1946; Indigenous progress in 1967; territory voting in 1977; and same-sex marriage in 2017.

Wednesday's result of 61.6 per cent "yes" to same-sex marriage shows that perhaps Australians are no longer easily scared by far-fetched claims of the sky falling in. That is perhaps because, in the 18 years since the last unsuccessful referendum, a greater portion of the population has tertiary education. There was a strong correlation between higher education and "yes" voting. Perhaps our politicians can be a bit more adventurous, especially with much-needed constitutional updating. The flight from the main parties is not a retreat into social conservatism, despite Donald Trump, Brexit and Pauline Hanson. Rather, it is an expression of dissatisfaction and frustration with parties that have not seemed to have done much recently. Loading That dissatisfaction and frustration can only transmogrify into outright anger if politicians, having put us through this expensive unnecessary process, muck about with the result.
