I've lived in the rural South, where there are lots and lots of folks who are religious fundamentalists. Let me share some insights from my own observation.
It is true that the fundamentalist model for the family is that the man (husband, father) is the head and religious leader of the household, and that the woman (wife, mother) ought to submit to the husband and obey him. The biblical authority for this (for a fundamentalist doesn't believe anything unless there is biblical authority) is Ephesians 5:22-24: "[FONT=&]Wives, submit yourselves to your own husbands as you do to the Lord.[/FONT][FONT=&]For the husband is the head of the wife as Christ is the head of the church, his body, of which he is the Savior.[/FONT][FONT=&]Now as the church submits to Christ, so also wives should submit to their husbands in everything."]
In theory, this is a patriarchal arrangement, since the man is the leader of the household. In practice, however, many times you have a more matriarchal situation, where the woman is the spiritual and actual leader---the stronger personality in the home--and the man goes along to get along. It is the woman who voluntarily wears dresses and has her daughters do the same; who drags the children and the husband to church on Sunday, though you would be surprised to know how many women carry the children to church when the father sleeps in.
So the ideal is to have the husband/father as the spiritual leader of the household, and I have no doubt that LT's preacher father was a very strong and dominant figure in her household, to the extent that it was abusive. That is the only kind of family that LT knew when she left home at sixteen to start her family with DT. And I think that she set out to establish that traditional hierarchy in her own home, and expected DT to lead, and taught the children to greet him in certain ways and to defer to "his authority." Notice that the sister said that LT made the children greet DT in certain ways, and she made the children smile before they could eat and all of that. She was the one in charge.
So I do think that LT was the dominant personality in the household, and that DT was the breadwinner and was more passive. THIS DOES NOT EXCUSE DT FROM CULPABILITY, because, even if he deferred to LT for 30 years, he knew better, he knew what she was doing was wrong, and he could have and should have stopped it.
[BTW, I bet we would find that DT's mother had a strong personality, too. A man is often attracted to a woman that reminds him of his mother.]
