I can't speak about how it is in other regions of The US besides the south, nor can I speak as a black woman or a breeder black woman, but here is what I have observed about black breeder women. While the white breeder women are generally breeding to fill the world with "Christian soldiers", the black breeder women are breeding to fill the world with black people thereby fulfilling the goal of their race eventually becoming the majority. Each rationalization is based in extreme racial and/or religious "power in numbers" type upbringings. Of course they BOTH like the attention and the welfare or perks that come along with it, but those are merely fringe benefits.
This isn't something they speak of often, (at least not openly) but it is one of the reasons that they want to breed, "for the cause", whichever it might be. One reason that whiggers who have mixed baybees are not well received by the black community is that they are perceived as "watering down" the black race and the more staunch black racists don't like it, even though they discriminate among themselves based on the lightness of their skin. One of the first things a black girl/woman will ask another black girl/woman when she says she has a new man in her life is, "Is is light?" or If a black male is describing his attractive new GF, he will say, "She's fine looking and real light skinned". The lighter the better among the black culture, yet they want a "pure race". I can't begin to understand the rationale, but then I haven't figured out how white breeders think yet either, and I am white myself.
I think that breeders of ALL races, regardless of their motives, are a different species than CF, but the chromosomal difference has yet to be discovered.
