My parents are Brits, I could be also although I’ve never claimed it.
Meghan is inconsequential. What ever influence she had/has had to fall on fertile soil, namely Harry.
The Royals are largely functionally cripples. Andrew can’t make breakfast and Charles has his shoelaces ironed every morning. Harry is different, he is functional. He just doesn’t want his life to be smiling, cutting ribbons to schools and hospitals. That’s what a “working” Royal does.
To blame this on Meghan or blame the Royals is misreading who the Royals are and who Harry is. BTW, if Harry is really a Hewitt, we are related and he’s part Ulster Scot, no other explanation is needed.
