These doctrines argue that husbands rule and reign over their wives because, as the teaching asserts, Christ is subordinate to God the Father who rules and reigns over His Son. The Father is the exemplar for men and the Son is the exemplar for women within this paradigm.
Why it's problematic
If someone's belief enhances their ability to love God and love others as they love themselves, making them good neighbors and with whom most can all live peaceably, it wouldn't matter. But I believe strongly that the belief system that Keller and his colleagues share deters both the understanding and love of God for the Christian and results in many varieties of harm to all people, especially to women. The teachings also foster a cruel, gnostic elitism that I've called "survival of the spiritually fittest." Though we Christians are called to be known by our love for one another, I am still often left speechless at the high degree of cruelty that the gender debate still fosters.
Ideas have consequences, and I find two most troubling consequences that result from these teachings claiming that marital sex concerns and mirrors the life of the Three Divine Persons in the Trinity. Some engage in this debate because these ideas hinder women from participating in ministry which is troubling enough, but these same ideas are used to dehumanize women which can also result in abuse. In terms of theology, I'm deeply disturbed by the theological implications. In effect, they result in a sub-Christian understanding of God's identity which robs Christ of His full deity
