She's a black woman - this is pure sour grapes.

Out of all ethnicities on dating sites, black women are consistently rated the lowest.

Plus, if they actually want to get married within their own ethnicity, they have to deal with... black men. So she's fucked from both angles, metaphorically speaking.

So, rather than say 'No one wants to date me(for reasons I'll never admit) and black men are horrible to deal with', she's just being a woman and trying to drag everyone else down with her.
