Imagine, please, an alternate universe where women occupy all the positions of leadership and power in the world and the Church, and God in Her infinite wisdom has chosen women, whose bodies alone can give life, as worthy of acting in persona Christa.  While the Holy Mothers are not men, of course in their wisdom they can understand men's needs and roles, and can design a theology of men.  They have translated the scriptures to say "women" and "sisters" but not to worry, that means all people.  St. Thomasina Aquina has taught that males, who can only spill seed, not actually bring forth life, are therefore mis-gestated females, poor things.  Even though males cannot be ordained, Holy Father Church is happy to have their talents in baking cookies, crocheting doilies for the altar, and answering the phone for Mother when she gets too busy.  Imagine this world and tell me a man would see no sexism, no sin, only a "recognition of fundamental differences."
