She has said some very misleading things, that's for sure, and some untruths were told, I believe, stemming from her "strong sense of self".
One such example is her response to Oprah when asked if Archie wasn't getting a title or his own protection because of his skin color. That's when Meghan sighed, and trotted out words to the effect that "all I know is that they were concerned about his skin colour and around the same time we were told that he wouldn't get his own protection or a title". Obviously I am paraphrasing there, but can she really have conflated a possibly unintentionally crass remark with the quite different explanations re the letters of patent and what this ancient statute meant for Archie? Meghan's disingenuous reply here - and let's face it she was either being disingenuous or stupid - stoked the accusations of racism that were levelled at the RF.
Another untruth, just number two of many, was Meghan's claim that a South African member of the cast of Lion King told her that there was jubilation in the streets at home when she married into the RF, very similar to when Nelson Mandela was freed. But Dr John Kani, the only South African on the cast, says he never even met Meghan, much less said anything of the sort. Cue a fruitless search for whom she may possibly have been speaking to. In this instance it might seem a bit harsh to say Meghan lied... I think she may have got carried away and embellished her story. Perhaps she did get a nice comment from the cast line-up when she met them, but not from a South African, and probably nobody made a weird parallel between Meghan's wedding and such a momentous occasion as the release of Nelson Mandela. I think that conversation existed largely in Meghan's head.
I wouldn't go so far as to say Meghan's been lying from the start. That would be a bit harsh, and some of the things she's been saying have been true. What I believe is that she's a bit of a fantasizer at times, she likes to spin a good tale. So she'll embroider a truth or pretend to misconstrue a comment to advance her own narrative. And I think, in so far as you are convinced of the truth of what you're saying, it's not lying... because lying is to intentionally mislead, and I think often she's the one who is misled, or confused.
