I was trying to ask why is Ireland apparently unique in the way it has moved away from being arguably the most Catholic country in the world to one where the power of the Church is a busted flush? This dramatic decline has not been matched by the Church anywhere else although the abuse committed by priests has been exposed all over the world.
I think it says something about how difficult large scale indoctrination can be even with complete control over the education system and providing the social cement of most communities. For example, some people seem to think indoctrination can be achieved simply by scanning a newspaper like the Daily Mail every day. In voting for same-sex marriage, acceptance of abortion and electing a gay PM indicates that indoctrination is no easy matter.
The changes here have been fairly dramatic in the last 20 years. My take on it is there were a number of factors that came together at the right time that helped accelerate what is probably going to happen in most civilised countries anyway.
With the country having been colonised and run in a somewhat less-than-mutually-beneficial manner for 800 years or so, there is and always has been a legacy of people being a tad sceptical about 'other people's rules'. Live in Ireland for any length of time and you quickly get a sense of how the locals tend to take most rules as advisory at best, and always with an underlying suspicion as to whether the rules are being imposed by somebody else in their own best interest.
In the early noughties, following a number of revelations about corruption throughout the political sphere, there were a series of high level Tribunals which showed pretty clearly that some of the most Senior Govt figures (including a number of Ministers and the then Taoiseach/PM) had their snouts well and truly in the trough. Despite having thrown off the Colonial shackles, there was a growing sense our own State (and Church) Institutions didn't really seem to be operating entirely in the best interests of the population as a whole. Those Tribunals opened up an extremely wide-ranging debate on power and authority - with the perhaps not entirely expected consequence that people began to question the role and bona fides of all of the various bodies that had laid claim to authority since the State took control of its own affairs back in the 1920s.
The country is a small one, with a total population less than 1/2 the size of London and perhaps 2-3 degrees of separation (at most) between any individuals living here. Once the lid had been lifted, it didn't take too long for the wide-ranging tales of abuse in all its forms to come tumbling out of the woodwork. Against the backdrop of the political classes trying to clean up their own act and distance themselves from the bad old days, there was no way the State was going to step in and continue to try to protect the Church, and so it all began to unravel.
As you rightly point out, we have a new generation of politicians in place, and they very successfully tapped into that desire for change and used it to further unseat the old lot, and create a new norm here. Throw in the fact that most of the under 25s are fairly well educated, see themselves as modern Europeans with a genuine say in how they would like to be governed as opposed to being ruled by a local cabal of seemingly self-serving politicians and similarly self-serving religious organisations, and you could say the country is finally starting to come of age.
