What I was meaning that 'Civil Unions' in New Zealand, from what I can understand (this via news coverage of the topic), deny the man/man or woman/woman union adoption rights/approval by the 'state'. It probably in the end comes down to that issue. Kids.
It sounds like it could eventually go to a referendum for it to have equal rights as marriage, but most likely it will go to 'conscious vote' of the parliamentarians, but those involved in a man/man or woman/woman union want to abolish 'Civil Union' and want it recognised as Marriage.
However, even though the 'conscious vote' of our elected representatives is fine, that's what they're elected for, sometimes the way the vote goes in that scenario will go the way of the loudest minority view (likely to be the regilious believers), and the silent majority doesn't play it's hand.
In the end of the day it will come down to an individuals view, if they're against it, they will never call this union a 'marriage' per se, and as cliche as it is, you can lead a horse to water but you can't make it drink.
To carry the cliche on, I suspose it really doesn't matter if the couple is man/woman, man/man or woman/woman. How the kid grows up, and if it becomes a productive, law-abiding member of society, will be dependant upon how the couple are themselves, also crucially also the kids individual beliefs.
Do we ever get to a Utopian society where is a licence to breed? But I guess that is a different topic.
