I concur with Janet Albrechtson that same-sex marriage should have gone to a referendum long ago, but disagree with her view that the issue is not about a human right (12/8).
What then, is it about? Equality before the law with same-sex marriage implies recognition and respect for human beings irrespective of sexual preference, among other things.
Freedom of choice for the LGBTI community should be the same as for the rest of us; all other arguments irrelevant. Same-sex marriage is quintessentially about human rights and subsumed in the definition of equality as enshrined in our democratic laws. Anything less than that makes our democracy a farce.
