You only have to look at the Lady Sarah Hussey debacle.
About 10-20 years ago, the narrative spread that it was wrong and racist to ask people of colour where they were from. This was happening mostly in America and GB. I always thought it was ridiculous, because it's a perfectly normal question and a good ice-breaker when two people don't know each other and want to chat.
I never had a problem with it. I would just say, I'm from (Caribbean coubtry) and I'd be delighted if more questions come, as that means the other (white) person is interested and I'm always happy yo talk about my home coutry. So what if it implies I'm an immigrant? I am! Or else, in the UK, my parents or grandparentes were, and that's fine, it's reality!
Over time, it became OK for a white person to a to ask a person of colour where they or their family are "from", ie, what is their country of origin. After all, lots of white people also come from somewhere else. No problem.
But after the Ngozi kerfuffle, that whole line of discussion has become a hot topic once again. I see white people thoroughly disgusted at the way it was blown out of proportion and thinking that people of colour are sensitive snowflakes so easily hurt and offended it's better to not say anything, avoid any discussion on place of origin, and so on. Support for Lady S was overwhelming, and anger at Ngozi, and disgust at those who play the race card.
The connection to the Sussexes? of course. Ngozi is an ardent Sussex supporter and the timing of the incident was no coincidence. It added fuel to the narrative that the RF are all secret racists.
My take:
If people of colour, or mixed race, make a fuss of every little tiny incident, as happened here, and as happened in the Oprah interview (they asked what colour my child would be!!! Waaah! Racism!) It detracts from the very serious topic of true racism.
In my life, I'm in my 70s and mixed race, I've encountered several incidents of serious racism. Not many, but enough, such as being denied a flat we wanted to rent after the landlord met me, having already accepted my white husband as a tenant. THAT is racism and needs to be exposed. It is rare, but happens. We have to be mature enough not to fly off the handle because of some harmless, probably well-meaning, statement such as "what colour will the child's skin be?" and "where are you from?"
When people of colour get all huffy and protective and walk around with chips on their shoulders, seeing racism everywhere, it's terrible for race relations. Blaming the victim? Not at all. Once you lose that chip you see that most people are actually not at all out to get you.
