This is only my second post, but I do not wish to offend anyone. But, the question was presented.
Multicultural is by true definition, multi-cultures. Meaning than one culture such as Irish, German, English, French, South African, Zimbabwe, Japanese, Chinese, Korean, etc. It also means, cultures of England, Scotland, Wales and Ireland. So, as we little people that the world governments wish to keep in order and from allowing businesses make money globally, they have misused the term multicultural and added race to it. The real term that most are talking about her is multiracial. Many more than one race, whether it is a multiracial town, state, country or person.
I feel that it is okay for a multiracial town, state, country. But, not people. So, I do not hope that Harry and Wills will ever date outside their own race. That may result in a multiracial child and I don't follow that route. I find nothing wrong with having multiracial friends, but dating is what it is in that it is trying out someone which may lead to marriage and children.
I like the family the way it is. However, I would like to see them become more multicultural like Harry and Chelsy (British and Zimbabwean). And I think, isn't Kate from the US? So, that would be British and American, if she is from the US.
So, that's my reply to the question, without trying to offend but giving my two cents.
