First of all, if you draft women and have them working in domestic support positions, that frees up more volunteers for the front. Secondly, women have fought long and hard to receive recognition as comparably valuable citizens. Including them in the draft would not be "payback" for the men that opposed that movement, but rather acknowledgement that women are just as crucial to the existence of this country as anyone else. To ask for an exemption would be to admit that equality is a principle enforceable only if it effects a positive result on women.
That said, I am one hundred percent against women in combat roles. Now or in the future.
