The relationship between Meghan and Harry is historic as Harry is the son of the King. I think it is unsurprising that so many people are interested in their story and in understanding why they are behaving as they are. I think Meghan and Harry both understand that their life stories will be part of the historical record and I think that is why they keep trying to "correct" the public's understanding of what really happened.
Intuitively, I feel for Meghan. I'm American so there's a lot I don't understand about the Royal Family, and I understand that the information released to the public is highly massaged on all sides to present a particular view. Life in the USA and life in Britain seem very different to me and personally I would not be happy living there, especially in the sorts of restricted social circles that Meghan was in.
I also think one of the things that might have happened with the official security, is that their estimation of the danger to Meghan and her children maybe was different than Meghan's estimation of the danger to herself and her children. And as a mother I completely understand why Meghan would get those internal senses that "I have to fix this" that all mums get when we feel that instinctive need to protect our children. I would not want my children's safety to be under the control of other people, especially if I felt those other people were unconsciously racist, or if I felt there was a hierarchy of whose life was more important. My child's cousin might be a future king, but you better believe I would fight for my kid just as hard as the future king's mother would fight for him. And I'd do so without apology.
On the other hand, I think many of her and Harry's choices about their public image have been deeply misguided. And the choices seem to make the same mistakes, again and again, no matter who is handling their public relations. The airing of private family matters in public, for example, I think that is very regrettable. Surely, Meghan and Harry, with their concern for their own privacy, would understand how important it is not to share private conversations with family members out to the public. Rumors are one thing, but confirming those rumors directly, opens a door to internal family workings that is not really fair, I think.
Still, I don't take as truth any of the public conclusions about Meghan or Kate. We don't know any of these people, really.
