1) Theological anthropology
Essential to this feminism is the belief that we are all the literal children of God, women and men alike, with infinite divine potential. This means that anything which gets in the way of the development of that potential, or undercuts the full humanity of any of God’s children, is something to be resisted.
We are also eternal intelligences in our own right, and agency is an eternal principle. It pre-existed the war in heaven, which was fought to preserve it. This gives agency a particular importance, even sacredness.
Additionally, because of our eternal nature, one could make the case that we have an inherent access to moral law (a knowledge of right and wrong); in any case, we clearly have this in mortality, as the light of Christ is given to everyone (see Moroni 7). This means that we can take our own moral judgments seriously.
