Oh look, a measured, considered post on Mumsnet's race problem.
And right on cue comes @LoisLane66, first, with a dog whistle, and then to deny the identity that Meghan has had her whole life as the child of a black mother and a white father and to reclassify her as "more than 50% white".
What gives you the right and freedom to think you can reclassify someone's race? Your long experience with the Race Classification Board of apartheid South Africa perhaps? Or was it your internship with Mengele?
Can't we get past all this
No we cannot.
For as long as your country and its white majority is unwilling to discuss the legacy of slavery and colonialism, this will not go away.
A whole continent, the largest continent at that, was governed by the British, the French and others on the basis of racial segregation, white superiority and black inferiority. Entire islands in the Caribbean are peopled today with the descendants of slaves, of black men and women who were shipped across the Atlantic as cargo to be bought and sold at auction, with black women raped by their white "masters" to produce slave children, who were considered black because they had just "one drop" of black blood in them.
Our societies were upended on the basis of race, our modern nations established on racial lines.
Black people live EVERY DAY with the legacy of slavery and colonialism, and in Britain, there are people like you who won't even have a conversation about it. worse, who, when told about racism, simply dismiss it.
So no, the race question is not going away. Do what America did. Take it on, look it in the eye, discuss it.
Listen, read and learn.
And do better.
