There is hierarchy in any partnership, the question is whether participation is voluntary or coercive. Flat out 50/50 responsibility creates no ownership over projects or leadership.

Though in Christianity, the partners become one through a mutual love for God. So yes, partnership is achievable under Christian Praxis.

Many social, and inherently moral, questions are dependent upon metaphysical worldviews. Secular philosophies tend to be morally relativistic, so there is no "right or wrong". At best they can be Absurdist with a preference to a particular Theological Tradition.

Be wary of philosophical foundations that revolve around power dynamics. Destruction is the net outcome, in the long run, when motivated by Power.
