I don't find this to be full of racist generalisations as someone else has commented . I find the point aptly made; that our abhorrence for individual rape incidents should not obscure the matrix from which these incidents spring; the "rape culture" as the writer puts it. 

When a woman is cat-called, when every passing man feels he has to make his presence known to you, when you are approached, touched, called out after and when comments of a sexual nature are muttered under the breath as you pass, we have a culture that makes rape possible. Mosiana is simply directing our attention to where the problem starts. Once we can agree on that, we can analyse how this situation came to be; but we need to see and agree that this is the reality, and that society's responses to it are racially biased. 

To say that it is racially biased is not to gloss over the rape of white women. All rape is horrendous; and for both black and white women it springs from the same patriarchal assumptions.
