Why do we still have the Queen of "United Kingdom" in Wales, Scotland and Northern Ireland?

What the ignorant say makes no difference to the actual fact. americans will tell you that the Second World War started in 1941 but, those who know say that it started in 1938. Why let ignorance get to you? You know what is right, I know what is right. When I hear an ignoramus speak, I just shake my head in sympathy. I can't be bothered any more, there are 6.5 billion to teach, I don't have the time or the energy nor even the inclination any more.
