"Ireland should have a say in the governence of six of it's provinces"
The Irish Republic can govern all its provinces, but not the 6 counties of NI, unless the people of those 6 counties want it.

You are obfuscating by using the phrase "have a say"
That is what you said mainland Britain should have, but you then said a say did not mean a vote??!!
And you apologised for the confusion it caused.
And now you are doing it again.

So we have a rough idea of your position, do you believe that, if the Republic wanted NI but NI did not want to join the Republic, their wishes should be trumped by those of the Republic?

Please do not answer with refernce to Cromwell, Easter rising, etc.,etc.
