The lies all crash into each other.

How can one say simultaneously that women are exempt from positive time bound commandments because they are spiritually superior to men and that the women's role is just as holy as the men's? If you are going to say that women don't need the mitzvos then their role must be a less holy one, almost by definition. In other words, men need these mitzvos for a boost. Thus, the woman's job is not as spiritual as it doesn't give a boost. Thus, to tell women that their role is just as spiritual conflicts with the idea that they are more spiritual and don't "need" the boost. Now you see why they want to put on tefillin. This is where flattery gets you. The lies all crash into each other.

The fact is that while women don't do positive time bound commandments they do something else: chesed. Doesn't chesed produce spirituality? It's not as if the women go and play tennis.
