It could get more difficult, but I hope other EU countries would step up and offer help in that case. (Can Irish women get abortions on the NHS? Is that why they can't travel to France instead?)
I hope the EU will force Ireland to give women human rights somewhen soon, anyway.
For all that Brexiters complain about EU regulations, the EU does not nearly enough regulating. I could live being in a club with a country that uses regular lightbulbs, but a country that treats women as subhuman breeding machines? I really resent that.
