There's been a great deal of talk in the last year, as a result of the Black Lives Matter protests, about racial inequality in various areas of society, and many genuine concerns have been raised. But no-one ever suggested that there was any connection between racism and Archie's style and title. That's because there isn't. And, in claiming that there is, Meghan does nothing to help people who have been the victims of genuine racism.
Until Meghan made that claim, had it ever occurred to anyone here that Archie wasn't a prince or HRH because of his ethnicity? Or had anyone ever heard anyone else make that suggestion?
The rules on the use of royal titles and styles in the UK, despite discriminating on the basis of gender, never discriminated on the basis of race. Even if the rules were changed in the next reign to restrict the HRH to children of the heir, I doubt anyone would have associated that to race or a casuistic move to target Meghan's children specifically.
