My sisters were fairly feminist by LDS standards and pointed out that, by this standard, the speaker was treating his wife as a servant.
recently in another thread we have been discussing the "Peace Maker" pamphlet. It is a pamphlet published in Nauvoo that pushes and defends the idea of polygamy. It is thought that JS had some hand in getting the pamphlet published but wanted the ability to disavow it if necessary. The "Peace Maker" suggests that polygamy will restore men back to an exalted position, rather than being dominated and manipulated by women.
There seems to have been an idea floating around in some corners of the church over time that there is a family hierarchy and men are at the top.
However, it feel like many/most men in the modern 21st century church are supportive husbands and present and involved fathers. How do we explain this?
1st I think that there were probably always men in the church that approached family life with their spouse in fairly egalitarian ways. Heber C. Kimball and his wife Violet seems to have been one such example - even in the age of polygamy.
2nd I believe that Church leaders began making statements to the effect that family life IS a primary duty of priesthood holders.
Elder Packer 1989 (most of the remainder of this talk is somewhat offensive by 2020 standards but I suppose change has to start somewhere)Holders of the priesthood, in turn, must accommodate themselves to the needs and responsibilities of the wife and mother. Her physical and emotional and intellectual and cultural well-being and her spiritual development must stand first among his priesthood duties.
There is no task, however menial, connected with the care of babies, the nurturing of children, or with the maintenance of the home that is not his equal obligation. The tasks which come with parenthood, which many consider to be below other tasks, are simply above them.
Elder Scott 1999As a husband and worthy priesthood bearer, you will want to emulate the example of the Savior, whose priesthood you hold. You will make giving of self to wife and children a primary focus of your life. Occasionally a man attempts to control the destiny of each family member. He makes all the decisions. His wife is subjected to his personal whims. Whether that is the custom or not is immaterial. It is not the way of the Lord. It is not the way a Latter-day Saint husband treats his wife and family.
I feel that statements such as these have served to make LDS men more invested than most in the task of child rearing and providing support in family life.
If there was a faction in the church that was against men changing diapers for what they saw as doctrinal reasons and another faction that was in favor of men changing diapers for what they saw as doctrinal reasons, then it would seem that that latter group won out.
