@phuzz:"Putting on my pedantic hat for a moment:
Irish citizens living in the UK did get to vote in the Brexit referendum, (but that was because of the Good Friday Agreement, not a specifically EU related reason.) Also, up until the other day, all UK citizens were also EU citizens and we all got to vote."
Sorry Mr. Pedantic, you're dead wrong. You might not be aware that Ireland and the UK have an, um, shared history which predates the GFA by a few years
Section 2 (1) of the Ireland Act 1949:
It is hereby declared that, notwithstanding that the Republic of Ireland is not part of His Majesty’s dominions, the Republic of Ireland is not a foreign country for the purposes of any law in force in any part of the United Kingdom or in any colony, protectorate or United Kingdom trust territory, whether by virtue of a rule of law or of an Act of Parliament or any other enactment or instrument whatsoever, whether passed or made before or after the passing of this Act, and references in any Act of Parliament, other enactment or instrument whatsoever, whether passed or made before or after the passing of this Act, to foreigners, aliens, foreign countries, and foreign or foreign-built ships or aircraft shall be construed accordingly.
