Is the assumption that nearly everyone in the southern states was evil? Obviously many of them were good and decent people, but they grew up and lived in a society with a different morality. Any story set in that society should reflect those beliefs. Otherwise you just get people with twenty-first century outlooks swinging swords.
This may be true, but it's going to be hard to convince someone who has been on the receiving end of that institution, or who is still suffering today because of it.
It's one thing to accept it intellectually. It's another to read a book where everyone like you is categorically inferior, because that's how nearly everyone felt back then. Take, for instance, a book where everyone just takes for granted that women are useless for anything except making babies, and their role (in fact) is to pop out babies until they either die, while doing a few very traditional female things that are widely regarded as less important than the Things Men Do, and that a man has the right to beat his wife etc., and in fact, she should be grateful to him for loving her enough to offer firm moral guidance.
Yes, I can possibly understand intellectually that this might be true in the time and place where the story takes place, and that most people (even the women) just accept it and manage to be happy in their inferiority. But it still gives me a sort of sick, panicky feeling. I don't enjoy reading it.
And I had no idea there were virtually no home-grown abolitionists operating in the south. I'm curious if there are any data about how the individual slaves felt about their status as well and whether most of them were, in fact, content with their lot. We get narratives about people like Harriet Tubman and Fredrick Douglas, but of course they're the people who escaped.
How happy can you be if you are viewed as inferior by those who have complete control over you? Even if they treat you well now, how secure will you be knowing that this could change in an instant? This is not a trivial issue.
This is something I wonder about too, both re slavery and categories of people who are considered inferior (like women). The constant fear thing. I had an argument with someone about patriarchy and whether it was inherently bad. I argued that it was, because when one group of people is in authority over another, the inferior group is always afraid and vulnerable. He said only if the leaders are cruel or abuse their power. I pointed out that some always will, and in fact, having power over someone invites abuse of power. He disagreed, stating that male abuse of women is actually a sign of a man corrupted by the weakening of patriarchy, because he's been robbed of the traditional virtues of his gender (protection of women and benevolent authority). Eck!
He pointed out that children don't resent or fear their parents for being in charge of them, if the parents are gentle, fair and loving (I wonder if he thought abusive parents only exist because modern society has robbed them of their traditional role and virtues).
I'm not sure I buy this. I know I resented and feared my parents, even feared them sometimes, even as I loved them. Even when they were acting in what they honestly thought was my best interest (and perhaps were). Being a kid was bewildering, sometimes frightening, because I had to go along with what grown ups wanted, no matter how I felt about it. And there was always that fear of breaking some rule I didn't understand and being punished for it.
And as a child, you know that someday you'll be a grown up and be your parents' equal.
A slave (unless it's a temporary indenture type of situation) or a woman, or a member of a lower class/caste or whatever will never, ever be free or equal. They may be able to rise in relative status within their lowly caste, but they'll
never be equal to their masters. Perpetual childhood. Even if they accept it as the natural order (the way we usually did our parents' authority when we were kids), they may still have been bewildered and afraid a lot of the time.
