Don ' t know why you have such a dismissive attitude . Any referendum on a united Ireland would be for all six counties and no less . There ' s simply no basis for it happening for each individual county . Catholics are due to overtake protestants in the next decade , and while that doesn ' t directly correlate with the amount of support for reunification at this very moment . It does mean that unionists will be in the minority . Add to that the rest of the UK dragging NI unwillingly out of the EU and possible although probably not likely . I can ' t say Scottish independence and you really can ' t predict how much support for a united Ireland could change in the near future . I . e . there ' s no need for a dismissive attitude when we ' re in unknown waters .
