I think this focus on everyone becoming 'caramel coloured' is an emotional response to distance the individual from their ethnic group that they consider racist. One often sees it in the white liberal generation that lived through the civil rights movement.
My own view is that it is a type of cultural regressive domination, the emphasis being that one must marry in to the dominant ethnic group in order to progress. This is not equality of opportunity, this is predjeduice.
In America native american women were encouraged to adopt white culture and have white husbands, in order to assimilate and 'breed out' the native american culture.
Black slaves were raped by their white owners in order to 'increase' their property.
Now we have cultural appropriation, which is not respect and understanding of other peoples differences but a commercialised, distanced and shallow parody of other cultures and people.
The act of crossing ethnic and cultural divides in order to have a relationship with someone you are attracted to is, of course, a good sign of equality of opportunity. But the idea of a culture of everyone being 'caramel coloured' is really about watering down what we find threatening. And is not true understanding of other people differences, and celebrating them. Our very survival depends on our diversity on a genetic level, it is the reason no disease will ever wipe us out.
Part of this fear is capitalistic i think.
