i guess one of the OP's essentials is that Black men (Bm) and white Women (wW) can conceptually be seen on the same (social) level by some. Of course that concept is not real either, just a construct that some of the Bm and wW may have in mind. i've read an interesting article about the American South that assumed wW and Bm would have a deeper understanding of each other's life situations because they both feel a somewhat lesser social status in a white patriarchal dominated community, perhaps for the institutional and personal racism and sexism each experience at times.
Food for thought: Do you think that concept really is in people's minds, and if so, may it have an impact on the connectedness and (sexual) attraction between Black men and white Women?
