I live in the border county of Fermanagh and to be honest I don't think a lot of people here want a United Ireland.
Ireland's already a sunken ship economically - yes, the UK isn't much better but in the current economic state i'd say most southerners would oppose a United Ireland due to the fact that they get an excellent exchange rate in Northern Ireland.
Southern Ireland is so different to Northern Ireland it would take years to change and implement schooling, taxes etc and there would be a lot of protesting.
For the person who said UDA/UFF are stone cold killers, what about the Omagh or Enniskillen Bomb? The IRA didn't even care if they killed their own people for a United Ireland. I take the stance that both sides are terrorists and are as bad as the other.
Northern Ireland really still isn't at peace, so why ignite pure and utter violence again with a United Ireland?
