Annepl,
I agree with almost everything you write. I, too, was an Alliance voter when I lived in NI and I believe very strongly in integrated education.
I'm a "Northern Protestant" living in the Republic & I 'd just like to mention one point relating to your last post: there is a 100 euros charge at A&E in the Republic for some. However, not if you are sent by your GP, not for most children and not if you have a medical card. My husband & I both have medical cards, although we are both retired professionals with good incomes. If you do have to pay for medical treatment, you can claim it back on your income tax. Like around 50 per cent of people in the Republic, we also have private health insurance, because the health service here struggles, but I can pop down to my GP anytime for free.
It really isn't as bad as many in the north think. Also the state pension here is higher than in the UK, as are other benefits.
So be reassured, things are better in the Republic than many in the North believe, & it's a great place to live & bring up children. Mine went to multi- denominational schools.
