Each race must carefully maintain its racial purity.
Yes, a mulatto is black, but the blood of another race in her blood, this can negatively affect many aspects, including physical, mental and spiritual development.
I recommend that you find a black one like you, so that it is free of admixtures of blood from other races, then there is less chance that the child will have physical, mental and spiritual problems (deviations).
I have seen many mixed people, and many of them have serious abnormalities, which are also expressed in physical diseases (deformities).
