What’s changed in Britain since same-sex marriage?

Four years ago, amid much uncertainty, 400 British members of parliament voted to redefine marriage in the United Kingdom.

Then prime minister David Cameron announced that, despite having made no mention of the issue in his party’s pre-election manifesto, it would be MP’s who decided the fate of marriage.

Now, it’s Australia’s turn to choose. There’s one key difference. Unlike in Britain, it will be the people who decide.

Everyone agrees, whether they admit it or not. This is a decision of enormous significance.

Therefore, it seems sensible to analyse the consequences of the potential change, within nations in which redefinition has previously been carried out.
