When people ask me why I hate the Irish, I tell them for two reasons: Catholicism and the IRA. If you want to be a citizen of the Irish Republic, walk your A-double-S across the Ulster border and apply for citizenship--it's that simple--and no innocent persons get hurt. How's that for a plan?
The fact that there is any terrorist organization in a Christian country is a travesty, but when one looks to the Inquisition, the Crusades, Slovakia in WWII--well, let's just say not everyone who calls themself a Christian, or who thinks that they are one, is one according to Scripture...
A united Ireland has little appeal to those in the Republic and would have little impact on the EU.
The IRA is just another tiny malcontent group in the EU like the Basque Separatists, Red Guard, etc.
Only the pure criminal element and the tracing of their loot rates higher in the newspapers than the greyhound race results.

Yes, they will establish a 32 county socialist dictatorship through criminality instead - think FARC with an oceanic climate!
