A child born in slavery into a 2 parent household was a child born a slave. Did the specter of being sold to another master, away from parents, or that fact that your mom could be forced to have sex with someone other than your father have an impact on the household?
Different subject for a different topic.
All the pledge said was that it was sad that even a child born into slavery, as terrible and indefensible as slavery was,
had a better chance to live with a mom and dad in the home than does a black child now. It was their way of illustrating how deploriable the situation is now.
They were not saying that anything about slavery was good.
They were not dissing single parents or suggesting that a single parent could not do a great job of parenting a child.
They were not presuming that kids who lose their fathers for any reason are doomed.
They were not suggesting that there are sometimes very good reasons for sending the dad packing.
But they are acknowledging that the best situation for kids is to have a loving mom and dad home--daddy is important--and we should be promoting policies that encourage that.
If you want to argue that it isn't a good thing to have a dad in the home go ahead. But you better bring your lunch if you expect to persuade me.
