Documentary? You just made me spit out my coffee! 
One of the most fucked up movies ever made.
I would like to hear your thoughts on this. Please. 
Start another thread, I’ll respond this evening.
The numbers I’ve seen suggest that in rural plantations about 1-2% of the slaves were sired by white daddies. Mind you, these white daddies could be overseers or they could the actual slaveholders. According to census figures, about 25% of urban slaves either had a white parent or white grandparent. Don’t know how reliable this cite is but the numbers they use are consistent with what I’m familiar with.
But all this data tells us is how many slaves were produced by white men. It doesn’t tell us the frequency of “marital relations” between slaveowners and their slaves. I wouldn’t be surprised if many slaves aborted their babies or killed them, either at their own direction or the slaveowner’s (Because, afterall, what would the neighbors think?)
That’s what I would guess happend too.
It happens today, really? Don’t white women have, at least, the option of abortion today?
I’d say that’s a good educated guess, as it wasn’t unheard of post-slavery, pre-civil rights. Or she admitted to the affair, but her family quickly silenced her and got to some old fashioned abortioning if she was knocked up.
