The new law will denigrate marriage itself.
It will not give a seal of approval to homosexuals.
I am married but if it comes in can we find a new word to describe
real unions ?

The homosexual lobby might call it marriage, but it is a fallacy. Marriage is a biological act between a man and a woman as is birth and death which is registered by the State [meaning Commonwealth]. The registering by the State is only the contract of agreement between the parties it is not the reality of marriage. Marriages, births and deaths are recorded by the State for population / citizen statistics. What two people of the same gender do in their bedroom that does not affect population is not the reality of marriage.

Josephus,

(We've been through all this before when you were Philo)

Marriage is not a biological act.

It is a social mechanism.

Suseonline,
Because pedophilia and polygamy is currently illegal in Australia and punishable by law does not mean that things could change as was homosexuality once. Homosexuality is outlawed in most countries and polygamy is currently recognized by many countries, and pedophilia is accepted in some countries. What makes our marriage laws different is we are an enlightened Western Nation and believe in the equality of gender. Allowing homosexuality is not a modern attitude it is recorded as accepted by societies that existed 5,000 years ago. It is just we live in an educated society that sees the social folly of same sex acts.

Poirot,
Please identify what the marriage contract actually socially identifies as "marriage". Our Law states it is "between a man and a woman". What is it that a man and a woman exclusively share in their social contract?

You want to make marriage the contract and not the reality it does not stack up philosophically. Contracts registered by the State cover a physical reality.

LGBTI is going the way of the Trade Union movement and environmentalism, selling out to the bosses because they've come to an arrangement they can all live with.
Nobody builds up a brand without an intent to capitalise on it and the LGBTI brand, if you remember had a big setback due to AIDS, the equivalent of a mass recall of product.
The capitalisation and sell off of LGBTI is about 20 years behind schedule, a good many of the original entrepreneurs have also died but the small bands of loyalists and their successors have seen it through and are ready to sign on the dotted line.
This isn't a good thing for the simple reason that assimilation of these ever more eccentric movements and tendencies just prolongs the collapse of modernity and capitalism, the whole Zombie system will keep shuffling along indefinitely as long as there are new clients to prop up the Ponzi scheme. Legalising Gay marriage just buys them some time but it's now in a spiral of diminishing returns, today it assimilates LGBTI, then tomorrow "moderate Islam" or polygamy and the payoff decreases each time until they've scraped the bottom of the barrel and there's nothing left.
The explicitly stated goal of the regime at present is social cohesion, that statement alone should put "Gay Marriage" in it's proper context. The proponents of Gay marriage are finally throwing their lot in with the state because resistance and separatism have failed and up until now all their other demands on a tactical level have been met, the Gay liberators are at checkmate and they know it, Gay Marriage is a face saving exercise.
This episode should be studied by dissenters because it's a clear example of yet another radical school of thought capitulating to the Capitalist and Liberal mainstream.
