If those are your beliefs then by those premises alone you could fairly extend those properties between ANY two people, race classifications are hardly observed by Allah- and are also disregarded by the Qu'ran.
Your presumption that Black men and White women are not fitting to "become one with the Creator as well as becoming one with another person" is certainly not the way of Islam as Islam would encourage all people to become one with the Creator.
Sista- if it bothers you, it bothers you- thats ok. But dont let it get into your head in such a fashion that you'll need to adjust your religion to fit it in.
At the heart of the matter race is a lie and we should be more concerned with that than this - a mere consequence of the greater lie.
Ask yourself, do you have a problem with Black men dating Latino women or maybe Indian women, or "bi-racial" men dating anybody? Do you realize that biologically and scientifically there is no race variance among human peoples- as such the differences you're offended by are cultural and ethnic ones. Do you have a problem with Black men dating German or Irish women?
Unless you're willing to claim that any ethnicity is inferior to another then the only problem that remains is that "white" culture persists to perpetuate superiority ideology and you would rather Black men not fall for it.
well in that you have a legitimate concern- but please make sure that you're not falling for it either.
