There is a petition for the Prince of Wales title to be dropped. It seems that a significant number of Welsh people object to an English person being foisted on them - someone who really has no meaningful connection with Wales and who doesn't speak the language. The title is seen by some as a symbol of the previous oppression of Welsh people, who at one time were forbidden to speak their own language.
Having read the petition and the history of how the Welsh prince and his family were done away with, and replaced by an English man, I can understand their position.
Mollygo "I think" means the same as "in my opinion" so you are mistaken in saying some people would take issue with it. -
I think the death of Diana at a young age, and the traumatic manner of her death - along with the fact that she had children and her marriage had been a sham, was bound to elicit more emotional responses. The queen was 96 years old and had enjoyed a very comfortable life so, whilst many people respect that and feel a certain sense of loss, her death was expected.
