How can researchers be their own guardian?

Australians are surprisingly bad at thinking about the place of religion in society.
Australia has an apparent conflict between religious freedom and sexual anti-discrimination legislation. It is particularly prominent in three areas: marriage, education, and social service provision.
The sacrament of marriage that takes place in the eyes of God is a separate process from the state’s legal recognition of the coupling.
The sacrament of marriage does not depend on the law, which exists only to regulate the rights and responsibilities arising from the practice. For religious believers, same-sex marriage won't change their union.
Policymakers and the outcomes they produce can play a powerful role in shaping public opinion on questions of same-sex rights.
Government policies regulating sexuality play a significant role in shaping citizens’ attitudes about sexual orientation and same-sex relationships.

Plato’s Symposium in an 1873 painting
A Supreme Court justice hearing arguments over same-sex marriage cited Plato's stance on homosexuality. But what did Plato really believe about all sexuality? A scholar takes a look.
The world is recognising that the issue of same-sex marriage is a matter of what state law, not religious doctrine, says, to the extent that Luxembourg’s Prime Minister Xavier Bettel (right) and Gauthier Destenay recently married.
Same-sex marriage is about state recognition of the union between two people and is a political issue. Religious belief can apply in a church and in individual decisions, but not to a secular state.
