<<I thought homosexuals just wanted to live a quiet life.>> Not possible Fr.Joe with all you Christians, banging on their bedroom doors and peeping in their bedroom windows.

Wow Runner! hallelujah brother, hallelujah! Was that post the leftovers from your 'Eternal Damnation Sermon' you delivered from the pulpit yesterday?
Why don't you simply call on your god to do a Sodom and Gomorrah on the Irish? Problem solved, or have you already done that.

Foxy,
The truth is that the majority of people, including the Irish either don't care about homosexual marriage or are opposed to it.
The Irish result shows that slightly more (40%) people are disengaged from or disinterested in the issue than support it (37.2%).
Saying "I don't care enough about the issue to vote on it" isn't the same as "It won't affect me so I don't need to bother voting", all the Irish result proves is that homosexual marriage is seen as an irrelevant issue and that the lives of homosexuals and the way the live don't matter to most people.
That's not a victory for Gay activists, they've managed to estrange themselves from 40% of voters and totally alienate about 20% of the population altogether.
Once the Gay rights thugs start harassing the people who didn't vote or opposed them on principle as they're now doing in Northern Ireland the situation is going to deteriorate.

When I discuss this issue in real life people often ask what's next for Gays? There's your answer, the next phase of Gay activism is continuing their "long war" on traditional values and driving anyone who holds to those ideals out of business or hounding them from their jobs as in the case of Brendan Eich.

This is what Gay power looks like.

Jospehus, in direct answer to your questions:

1. Does it mean surrogacy and I.V.F. will also become a legal right?
No. There will be no change in relation to parenting rights and fertility service

2. Does it mean marriage celebrants within the Churches can be sued or found criminal for refusing to conduct a requested service?
No. The church will be free to marry, or not, as it chooses, just as it is now.

3. Does it mean that the State must now recognise all same sex couples living together as de facto and have the same rights as a man and woman living together?
It means that married same-sex couples will have the same status as married opposite-sex couples. Only people who have been through a marriage ceremony are married.

4. Does it mean the homosexuals have the right to violate the conscience of person under law to objection to perform a service for same sex marriage?
No

5. Does it mean the term marriage cannot now be used as a specific biological state between a man and a woman and is now merely an emotional state of a love union between and two unspecified persons?
Marriage has never been a biological state, nor a merely emotional one.

6. Does it mean social norms of "mother" and "father" cannot be used in birth certificates because gender no longer recognised?
No, gender is still gender.

7. Is the next step the legalizing of multiple partners; and the lowering of the age of marriage to pubity for girls
No

I'm pro, but I really have no idea what will happen... That's for some smarter people to judge.

"2. Does it mean marriage celebrants within the Churches can be sued or found criminal for refusing to conduct a requested service?
No. The church will be free to marry, or not, as it chooses, just as it is now."

That is indeed the status quo, but for how long?

I'm tipping that it won't be long before before Gerald Fitz Maurice and Maurice Fitz Gerald are claiming that the law discriminates against them because the Catholic Church is allowed to refuse to join them in holy wedlock.

Wherever homosexual marriage has become law it denies the right to discriminate which is the reason homosexuals want the term marriage. Therefore one cannot discriminate on sexual preference which will make a large part of the population criminals before the law if they follow their conscience. This takes us back to the 16 century conscience civil wars. Ireland is not immune from conscience civil war.

Rhian, You are simple and naive to what is actually happening by the homosexual reformers. Most homosexuals just want a quiet life but activists have another agenda, and that is to confront the traditional values that marriage is a biological union with the purpose to raise and protect children.
