Dublin - Ireland took to the polls on Friday to vote on whether same-sex marriage should be legal, in a referendum that has exposed sharp divisions between communities in this traditionally Catholic nation.Allowing gay couples to wed would be a seismic change in a country where homosexuality was only decriminalised in 1993, and where abortion remains illegal except where the mother's life is in danger."A lot of my gay friends want to get married. I feel it's a simple matter of equality," said Eoghan Bonass, aged 35, voting in a polling station in the south Dublin suburb of Milltown."This referendum has touched a chord. I've noticed there's far more awareness about this one than previous ones," he said.'This is about the children'Rachael Stanley, aged 60, said she voted "No" and felt "strongly about it.""This is about children. It's far too radical a step. I want to protect marriage and the stability of children," she told AFP."I hope I don't get tarred and feathered for saying that," she added.If the move is approved and the ensuing legislation is passed, Ireland would become the first country to make the change following a popular vote.Referenda in Croatia and Slovenia both resulted in "No" votes, although in Slovenia, parliament went ahead and approved gay marriage in March."We are saying here, in a world first, that the people of Ireland can extend the right of civil marriage to all our citizens," Prime Minister Enda Kenny said ahead of the vote.Ireland would be the 19th country in the world to legalise gay marriage and the 14th in Europe.Strong opinionsAcross the border in Northern Ireland, which is part of Britain, gay marriage is banned even though it is legal in the rest of the country.All of Ireland's main political parties, including conservatives, support amending the constitutional definition of marriage, and the latest polls put their camp in the lead."This burden and pressure that's been on (gay couples), living in the shadows - that can be removed on Friday by voting 'Yes'," Kenny said.But the result is by no means certain - the Catholic Church has campaigned strongly for a "No" vote, and many older and rural voters agree with the clergy.''Historical day for Ireland' "My voting 'No' is not a vote against gay and lesbian people, it's against changing the definition of marriage," the archbishop of Dublin, Diarmuid Martin, told RTE state television on Wednesday."I think you can have equality while recognising difference. For me, the fundamental thing is marriage and a family are about the complimentary gifts of a man and a woman, a mother and a father."The majority of Irish people identify themselves as Catholic, but the Church's influence has waned amid growing secularisation and after a wave of child sex abuse scandals that badly discredited the hierarchy.Voter Jodie Boylan, aged 41, said she was too excited to sleep last night."It's a historic day for Ireland. After all we've been through with the Church and everything else what a message it would be to send that we are all equal and can be treated the same.""I really hope it passes," she said.Accusations of foul play Polls close at 22:00, with the final result not expected until Saturday afternoon.Voters are being asked whether or not to add an article to the Irish constitution saying: "Marriage may be contracted in accordance with law by two persons without distinction as to their sex."The debate has become increasingly heated, with accusations from the "No" campaign that their posters have been defaced and their supporters vilified.The "Yes" side has been boosted by the support of sports, music and film stars including Irish Hollywood A-lister Colin Farrell and U2 frontman Bono.Irish expatriates living in Britain who are still eligible to vote have also started an online campaign, "Get the Boat 2 Vote", to encourage people to travel home and support the change.In another social media campaign, "Be My Yes", Irish expatriates who can no longer vote posted messages and videos pleading on their countrymen to choose gay marriage.Three opinion polls last weekend showed support for same-sex marriage ranging from 53 to 69 percent, while the "No" vote is hovering between 24 and 26%.
