Re: The status of Northern Ireland
"As I understand it, NI demographics have been gradually shifting over time and are now such that there would probably be majority support for leaving the UK"
I'm not sure you understand it very well, NI benefits enormously from being part of the UK, I'm not sure many people want to pay EUR 50 to see a GP. There's a lot more trade with NI & the rest of the UK than with 'the South'.
"I'm guessing the EU factors would also support remaining in the EU if/when the rest of the UK departs, as appears to be the case with Scotland"
You're not making the mistake of believing the SNP are you?
A large majority here still want to be part of the UK, our problem is the unionist vote is split 3 ways so the SNP get elected. And they're the only ones you ever hear from.
BTW, an independent Scotland would be out of the EU for a considerable amount of time, and Sturgeon et al would have had us all out in 2014 without a thought. The current bloviation is
just convenient grievance mongery.
