Indeed, Judaism has more than two paths. Each of us knows which paths are most appropriate for us at different times in our lives. It would be arrogant to presume we know which paths another should travel. Perhaps our energies are better spent finding the correct paths for ourselves. I think the journey is at least as important as the destination.
Biology is only part of destiny.
God, Torah, family, friends, schooling, jobs, talents, tastes and a thousand life experiences all shape the people we are continually becoming and the paths we know we must travel. Prescribing one of two rigid paths based only upon gender ignores the rich diversity of Jewish lives as people really live them. For me, David's metaphor conjures up a grassy plain with two parallel tracks worn by countless feet. Somewhere in the unseen distance both paths end, and those who walked them arrive as equals and receive their equal rewards. I prefer a different metaphor.
