You view of gender if fine Bill, it's a roll assignment that works for many people.   The facts are that not everybody has the same experience or are the kind of person that fits those rolls that work for you.   I know women that are lousy parents and men that are great parents.    

If you think God is in tune with nature, and I do, then you want people to follow their nature.     It is not the same for all men or all woman.  Stuffing them into a preset roll of somebody else's imagination that is Human and not from God, throw on the guilt of not 'fitting' the religious model, and having people in the church with condemning judgemental attitudes boarders on enslavement for those who just don't fit.   

I'm not telling you that your concept of the rolls in of men and women is wrong, lot's of folks can be found that support that and nobody should tell you that's wrong.    But you can't judge the heart and mind of others and you can't know God's judgement.
