Somehow I doubt slave owners kept many records. From the 1880 citation you can infer a lot about what was happening earlier.
Every slave owner a heartless ogre bent on breaking up every slave family. There are a few we think pretty highly of.
Failing to demonize every aspect of slavery from 1700-1865 is not apologizing for it nor will you wake up tomorrow morning to find it has returned because you failed to preach against convincingly enough.
Doing what you are doing amounts to moral exhibitionism: Demonstrating your superior morality by weighing in on an issue that was settled more than 150 years ago. What's next, tying Bachman to Roman coliseum violence?
The facts that show that slaves grew up with both parents. And you just said you doubt that those records exist, so how can you try to say that current stats are worse, when you dont even know what the old stats were.
The rest of your post is just you projecting. I never said Bachmann (not Obama) was a racist. I said she was stupid for signing something making a factually positive claim without showing any facts to back up that claim.
