Holy smoke, are you really failing to comprehend this badly. I was not attempting to equate "English person" with "citizen of the UK" (sheesh!!) Read what I wrote again. Here is what I was actually saying: you should not be thinking about it in terms of "the English" or "people from England". You should exclusively and solely be thinking about it in terms of "citizens of the UK". Whether those citizens are from the region of England, the region of Wales, the region of NI, or the region of Scotland.
Try the business merger analogy again - it might aid your comprehension. Remember, A and B merged in 2005 to form The United AB company. The former A and B are now nothing more than business units of The United AB Company.
To extend the analogy to your current misuse of terms, imagine again that the local management board of the B business unit (with the consent of the employees of the B business unit) would like to become independent of The United AB Company. Your misuse of terms is talking about "the board of A" or employees of A" being on the other side of the position of the local board and employees of B. But you should be talking about "the board of The United AB Company" and "employees of The United AB Company" - a set which, incidentally, also included the local board and employees of B. Everyone who is a direct stakeholder in The United AB Company (chiefly shareholders and employees) has a stake in what happens to the company (including whether or not B is allowed to spin off from the company), and the will of the stakeholders in The United AB Company is empowered and exercised through the executive board of The United AB Company (which happens to convene on the premises of the A business unit factory, by the way......).
Every person who is a citizen of the UK, is, in effect, a shareholder in UK plc. And we, the shareholders of UK plc, have elected an executive board (in the form of a national parliament and a national government made up from the parliamentary party with the majority) to represent our interests. If one business unit of UK plc wants to demerge and become independent, then the shareholders of UK plc have the absolute and fundamental right - via their elected board - to decide whether such a demerger would be in the best interests of UK plc.
Does this perhaps make things even a little clearer? Somehow I suspect not.............
