please go back to your original post as you are now twisting the reply you got .....Working on that theory the whole of Ireland should vote about N/I, south of border IRISH, North NORTHERN IRISH,
The point is the vote would be to determine Scotland’s future within UK, the UK being England, Scotland Wales and Northern Ireland . Wales and N/Ireland are as much a part of the union as England. Nothing to do where the border is.
Why would the English alone join the vote , I could understand the argument that the whole of the if the UK should vote, but not just the English.
