Why Not this?

why is it people are stuck in a confined very view have seen this with #britexit debate, they wish to only see possibilities in a narrow blinkered channel and there are so many combinations to move forward with.
For me what is wrong in discussing a new union of Ireland and UK alone with the other #commonwealth realms? Every thing should on the table and nothing excluded, even the constitution and makeup of all and any of the members I propose.
