As I said, God is not "male" in the biological sense. In this sense God is genderless.
God is called male, due to the nature of his inter-relationshp within himself (Father, Son and Holy Spirit) and towards his creation. Thus in regards to calling God "She" it obscures the theological truth regarding this relationship and God's nature in this regard: Thus the heterodoxy.

As to biological man being more like God, Humanity is made in the image of God in that our souls reflect the divine nature, we can reason and think. Likewise the totality of humanity is body, soul and spirit(mind) which reflects the divine trinity of the father (who I shall equate with the spirit), son (the body as Christ was made incarnate) and Holy Spirit (the soul).
Naturally this is an imperfect reflection and hardly is an accurate reflection of the trinity, but this triune nature of the humanity, although different entirely from the consubstantial relationship of the three persons of the trinity, it is an echo of that triune nature on the human scale.
And in regards to women that reflection of the divinity is equal to the human male. Either way though you can hardly compare humans to God. God is God and is incomprehensible beyond that which is revealed in revelation to us.
