With regards to titles, whilst not the standard for grandchildren to get them, if William and Kate’s children do then they should have been given ah explanation they could understand as to why there was different treatment but I don’t believe it was due to race.
They were given an explanation. Which Harry anyhow would already have been aware of.
Even M in her interview couldn't avoid a vague and dismissive reference to 'some protocol to do with I can't remember what who now maybe, like, George the fifth or something?' and then a sort of amused eye-roll suggesting an actual text of 'omg you see how bizarre and archaic and from the Dark Ages these pathetically restrictive 'rules' are? They could have called my son a Prince, like his cousins, but they refused! And why? Well, you KNOW why ........'
It was beneath contempt, and oiled all the while by Oprah, who I always admired and now sadly can't.
It was a study in deliberate fudging of the actual truth and direct insinuation masquerading as 'revelations' of 'her truth'.
Actual reality:
Harry knew his kids would not be Prince/princess until his father becomes king.
M didn't accept this and wanted Archie to be a Prince anyhow, as it wasn't 'fair'.
Presumably they requested it and were told no sorry we can't change this.
They were offered other titles - this protocol being that he could have a different title until such time as he became Prince (and bearing in mind that we have a very long-serving monarch and when the rule was set, it was most likely presumed that such children would most likely be Prince/Princess straight away as their grandparent rather than great-grandparent would be on the throne).
So it was/is just a question of being a bit patient, and being happy with a different title for now (talk about spoilt ...! Sorry ðŸ¤).
But no: they refused any title for him, explaining this publicly as they just wanted their child to be 'normal'. Thus suggesting they were too modern to perpetuate the whole (outdated) concept of titles.
But Prince would have been fine.? In fact, so much so that M did an Oprah interview about him not getting the title Prince and you would pretty much not be wrong if you were to conclude that she directly said that this refusal to call him Prince was because of her unacceptable genetic heritage.
Which is clearly bollocks.
