I don't understand these kinds of comments.
Just because your family wouldn't speculate about such a thing does not make it abnormal or racist.
Here's Trevor Phillips who says quite clearly that it's entirely normal and usual to have that in black families, and it would be unusual not to have experienced that rowing up in a black family in the UK.
Presumably he is not a fake black Mumsnetter as apparently all the people on the thread who have said the same thing are.
Now, whether or not you think he is right about why MM commented the way she did, I think it is fair to say he is an actual real British black person who has quite a lot of experience of black families, both African families and in the Caribbean, and he's not lived his life in some kind of white bubble, and isn't a racist.
My extended family is also very mixed, with quite a variety of different physical manifestations, and they talk about it a lot.
If some people don't like it they are entitled to their opinion, but this bizarre attempt to claim that it doesn't happen in mixed race families is bizarre. It does, and people know it does because they see it personally. A lot of people now, especially in cities, have mixed families, and often for a few generations.
