The Royal Family isn't just any family though. And actually as a mixed race woman I absolutely expected my white grandparents to not accept racisim directed towards me in their home. By their own children or their staff (if they had them).
I don't believe it was a racist comment. However, I don't believe in that family you can claim that many of them were racist but then also pretend it's nothing to do with the Queen.
He also was angry and hurt that, as they saw it, no protected them against the press.
I dont think they should blame the Queen. I dont think you can say 'we were the victims of the RF.....but the Queen is great and is lovely and always supported us'
