I'm not trying to trivialize slavery but force a recognition that's there's a hair's breadth difference between many instances of being a domestic slave and very many instances of being a housewife. One is demonized and the other is celebrated.

The way you hear a minority of Bible-enthusiasts talk about the role of a wife is in _no way_ different than the slavery described in the article.

While there may be some similarities, "no difference" is way too far. Even the most extreme fundamentalist at least in principle is going to acknowledge that Paul wrote in Ephesians that as Christ loved the church a man should love his wife as his own body. And in a more practical sense I can't imagine most of even patriarchal husbands would let their wives' teeth fall out and deny them dental care.
