Registering is not the same thing as being drafted, they need to register just like the men. Besides, half of women today will never marry or have children so no excuses.
Registration at this juncture is acquiescence to their views of womanhood. Once they can force women to register, they (the Pentagon) will find some reason to test it. The agenda in Washington and in today's military is to get women out of their homes, away from their families, away from their children.
Destruction or at least marginalization of the traditional (Bible-centered) home and family is key to the agenda.
