Find it so odd that all the details that have been put out there, and everything else that has gone before from this author? journalist? is consistently relayed with such personal animosity. Writing from the perspective of not liking a monarchy would be understandable. Writing from the perspective of disrespect for members of the family for specific behavior or patterns of behavior would be understandable.
Consistently writing in the tone of trashing various family members, often without citing reasons why so and so is absolutely such a villain is strange and doesn't convince on its face. When incidents are detailed they are usually framed as private situations where the same two parties are consistently wronged for absolutely no reason, aside from claims of jealousy from family members of their unquestioned public popularity and/or unrivalled ability to carry out royal appearances and duties far beyond anything imagined by the rest.
No matter what these people are actually like (my personal opinion is that in general they're all quite entitled and out of touch and I'm quite happy not to be a taxpayer forced to support them), nothing in any accounts by this writer pass a credibility sniff test.
