Of course, it was very intentional of Meghan Markle to link any supposed denial of the Prince title to Archie on the basis of alleged racism from the RF.
The plain meaning her words is very clear.
Meghan Markle claimed:
"....the first member of color in this family isn't being titled in the same way as other grandchildren would be."
On the contrary, Archie is really treated no differently to the Queen's grandchildren who aren't entitled to the Prince and Princess style.
Zara Tindall and Peter Phillips, for example, don't have this style. Zara is the Queen's eldest grandchild, by the way.
Furthermore, Prince Edward's children are NOT styled as Prince and Princess despite the Letters Patent of 1917. They are styled as children of the Earl - not HRH Prince and Princess.
Edward's children are the first to have the double barrelled Mountbatten-Windsor name.
Harry and Meghan's son, Archie, is treated in the exact same way as Edward's children AND he carries the same double barrelled surname as they do.
Here again, Meghan's implied claim of racism doesn't stand up.
Of course, Meghan incorrectly referred to Archie as one of the Queen's grandchildren. He was a great-grandson of the late Queen since his father, Harry was her grandson. Archie was treated NO differently to any great-grandchildren who WEREN'T entitled to Prince and Princess titles during the late Queen's reign.
It was deliberate to claim this from Meghan. She wasn't confused and she's far from being a stupid person.
