I do not know why you think army recruitment and your adventures on the border have any relevance.
Why will you NEVER stay on subject.
I will respond to parts of your ramblings.

"You bizarrely described my American Civil War analogy as an example of my being a 'fascist bullyboy', then ignored my invitation to qualify your statement – the invitation is still open"

The Confederacy wanted to be separate from the Union.
They were made to rejoin by force in a terrible war that killed more Americans than all its other wars put together.
And you think that a good analogy for what should be done to the 6 counties.
Fascist bully boy is quite restrained I think.

Scotland is mainland Britain, has been part of UK for centuries, but is free to leave any time it wants to.
Cornwall is Southern England. It only has a tiny Nationalist movement, but if that changed it could expect the same treatment.

You are now advocating that British people should decide Ulster's future! If I advocated that there would be howls of Empire Loyalist from you!

The 6 Counties have been under British rule for centuries. Never under Dublin rule. They know much more about their history than you or me, and overwhelmingly still want to stay British.
You and I might not like that, but I would let them choose their own future.
And you?
