In reality, if it wasn't so easy esp for the middle classes to get to the UK and access abortion services, this would have changed years ago.
It's why there aren't rape and incest exemptions, the only exemption is threat to life of the mother. It's obviously horrifying, but it is internally coherent. For all their faults, when Irish pro-lifers say they're pro-life, they actually MEAN it, unlike the "fair-weather" pro-life movement in the US, which, as is rightly said above, is inherently misogynistic. It does mean, though, that it (our version, I mean) is harder to push back against.
That said, I think that there is also a lot of hypocrisy at work - the fact that it's so easy (if you have the money - as Emmet Kirwan so passionately describes - ) means that although most Irish people have either had, or know somebody who has had an abortion in England - even my aunt did back in the 70's, for instance, and my pro-life-but-also-pro-choice father helped her pay for it - they can pretend that Ireland is "pure" and "moral" for not technically allowing it.
I'm obviously not actually suggesting this, but if the UK said "Guys, we know how important your laws against abortion are to you, and it seems like we're inadvertently undermining them. How about we ban access to the UK for all pregnant Irish women before 26 weeks, and enforce pregnancy tests on anybody who we suspect of morning sickness at our border crossings?" For how much longer do you think abortion would be illegal in Ireland? The Irish middle class HAS unfettered access to abortion, and as long as that remains the case, there is no need to rock the boat (to Manchester).
I've lived in the UK for 8 years now, and had my two children here. If I got pregnant now, I don't think I'd have the baby (getting on a bit, and my family is complete) and I could have an abortion right here in my own town, probably in the same hospital as I gave birth, safely, locally, able to go home to my own bed later that day. It seems so distant and impossible that in my own country, literally just a couple of hundred miles away, that would not be possible.
I don't like the €1 fine idea, though, because (even though it will never go through) it leaves the principle intact, and that's what we need to dismantle.
Side anecdote: When I was 18, I was "trouble". I wasn't doing anything to excess, but I dressed outlandishly (for my conservative working class family and older parents' sensibilities, anyway!) and there was general anxiety. My dad had the bright idea of a "bonding" weekend, and took me to London - we had a great time, saw the Reduced Shakespeare Company, saw the sights, had lovely meals, visited Carnaby St etc. Later I discovered, that my father's family all assumed that I had been for an abortion. The idea that Dad might just do something nice for me was impossible, but that I (a wild teen!) would be going for an abortion was a perfectly reasonable explanation.
