Finally - an idealogical difference between us. :-)
Unfortunately, yer dead wrong.
though it depends on where you draw the line for self-determination.
Protestants are a minority on the Irish Isle - give the whole island a vote and you'd have one country.
However, Ulster is still a part of Britain and has a proddy majority. Give Ulster a vote and they remain British.*
*until such time when the catholics have bred enough.
