As a beloved Irish-American would put it, this is a big f'n deal: the voters of the Republic of Ireland legalized same-sex marriage by a wide margin (62.1% yea, 37.9% nay). For a country with a populace that is over 80% Roman Catholic, this vote constitutes a real wake-up call for the Roman Catholic Church- there is a wide gulf between the pulpit and the pews, with the laity tending to be kinder and more tolerant that the clergy. Here in the 'States, approximately 54% of Roman Catholics support same-sex marriage. Even the Pope has lightened up on LGBT people.
It is hard to predict the effect that such an overwhelming rejection of Church dogma by a population that has traditionally been seen as orthodox will have on the Church as a whole. In Ireland, though, evidence of horrific abuse on the part of Church-run institutions probably played a factor in the vote, as did the sheer fact of demographics- in a society in which large families were the norm, everybody is bound to have at least one LGBT relative.
The one blot on this otherwise outstanding day is the fact that Phil Chevron didn't survive to see this day. His song Under Clery's Clock was a tear-jerker that described the risks inherent to same-sex attraction in a society which made such relationships illegal:
Good on the voters, now let's hope that this vote is just the start of a worldwide human rights campaign for LGBT folks.
