The results are supposed to be out around now, so I'll update OP when the proper results come in, but so far it appears a large percentage of votes are favored...in favor... of legalising same-sex marriage, according to The BBC.

EDIT: With a 62% majority, same sex marriage in Ireland has passed!! (1.2 million for, 730,000 against) It should be updated on the BBC link above, but I'll get around to it once I'm on my laptop.

Important bits below:

More than 3.2m people were asked whether they wanted to amend the country's constitution to allow gay and lesbian couples to marry.The referendum was being held 22 years after homosexual acts were decriminalised in Ireland.

Government ministers have said they believe it will pass, while prominent "no" campaigners have conceded defeat.
If the change is approved, the Republic of Ireland would become the first country to legalise same-sex marriage through a popular vote.

What a 'Yes' vote would mean

The Republic of Ireland has a written constitution which can only be changed by referendum. If the proposal is passed, a marriage between two people of the same sex would have the same status under the Irish constitution as a marriage between a man and a woman. They would be recognised as a family and be entitled to the constitutional protection for families.Civil partnerships for same-sex couples have been legal in Ireland since 2010, giving couples legal protection which could be changed by the government.However, if the vote is passed, married gay people would have a constitutional standing that could only be removed by another popular vote.

The referendum vote did spawn a good few laughs on the internet though, given by Dubliner Martin Duffy:

And what did the Westboro Bastard Church think on the likely result?

The only thing that is a bit disheartening is that the Churches will still have a choice on whether or not to wed same-sex couples, which Ireland being a largely Catholic country isn't just going to accept that. Yeah yeah whatever "Freedom of businesses/instutions to do what they want" and all that, but with 84% describing themselves as Catholic, there's bound to be a few gay Irish Catholics still with a problem of getting a "proper marriage", which sucks.

What is more interesting is how fast this has gone. Only 2 years before I was born was acts of homosexuality legally allowed, and only 5 years ago were civil partnerships instated. Compared to many countries, we've certainly picked up the pace and adapted to changing social/sexual acceptance of the world.

Oh thats cool. Ill keep checking in to see results. Im at work right now.

Ireland is majority catholic, yes? This is fairly surprising that it's looking positive. Ireland always seemed to be a stout place. I don't know much about their culture though aside from them beefing with the British. I'll stay posted.

As do Mosques and Synagogues. Should we start forcing those religious institutions to perform gay weddings too?

I know this isn't your contention Irish, but I'd really like to emphasize just how important religious freedom is and why the state does NOT belong there. It's fantastic that gay marriage is now decriminalized in Ireland, but let's not overstep our boundaries and start enforcing morality at gunpoint, even if the beliefs in question are religiously neolithic and outdated.

Enjoy the hurricanes.

Thank god it's passed. Having gay marriage illegal is totally stupid.
