I misread your question so my reply was unnecessary snarky.
Black male+white female is 2nd least common coupling in USA, this at least is a fact unrelated to my opinion.
Comparison to media rates is based on Hollywood blockbusters and Netflix lineup. While the numbers for Hollywood are lower than on Netflix, black male+white female is 2nd most common coupling in Netflix originals.
P.S. I am European and child of a mixed marriage myself, so this is no 'keep America white!' effort. It's just that the idea of 'forbidden truths' 1984-style rubs me the wrong way.
Is it a fact, or just your imagination? Does this fact come from statistics or your gut?
