There was been an interesting article in The Spectator saying that asked as a hypothetical question, given the choice between leaving the EU and breaking up Britain, which is more important. It turned out most would break up Britain. And that has been argued for on this very thread, when it was claimed most leavers would be quite happy to see Northern Ireland out of the U.K.

I believe The Spectator is a little more intelligent than to pose that question. The question was:
“If it were not possible to do both, which of the following would you choose to do? A) Leave the European Union or B) Keep England, Scotland, Northern Ireland and Wales together in the United Kingdom?”

The choice was between leaving the EU and saving the UK, not between Leaving the EU and breaking up the UK.
