@Idiot nationalism :"This is not about the English government hurting N.I./Ireland years ago; it is still going on in the occupation of N.I."
No, 'Ireland' as a geographic entity is an island in the British Isles, Ireland as an occupied country is a social construct. So it with me, 'I imagine a nation sate called Ireland, and it is occupied' - alas you are in the minority with this imaginary state. We live by the UN supported self-determination of people. The Republic (which i grew up in and live in now) makes no territorial claim over the 6 counties. No since 1998, when the majority voted in favour of the good friday agreement (94% in favour, though only 56% voted).
"And I think the brutality and discrimination the Irish have suffered at the hands of imperialism more than justifies that the land should be theirs."
No, this is not the principle which we use to determine land ownership, sovereignty or other empire building land deals. Nor should it be.
It is possible to claim compensation via various higher courts (the European court of human rights perhaps) and then use the money from the compensation to buy houses from the unionist majority (and i'm sure Polish claims from WW2 are still extant)
You should not be able to force people from their homes and committing the same crimes you accuse others of to get 'justice'
@Obiwan"Why not allow Scotland, Wales, and all of Ireland sovereignty, and form the UK as a sort of EU collection of these four?"
'England' or the UK has been fairly clear that it would not prevent Scotland from become an independant nation is it wanted to (as the Scottish Nationalist Party proposes) The Scottish people on the other hand have not been convinced (and the SNP have the power to hold an election whenever they want, they just don't want to lose..)
Equally, both the Irish and British governments have undertaken to respect the wishes of the people of northern ireland, if they choose to vote for independence/Union with the republic...
The most likely change in status of any of these nations is to become independent EU member states (though the UK might leave the EU and join the EFTA).
