Okay to be honest here, I'd find not much of a problem in allowing women into the draft. If they can pick up and fire a gun, use machinery, or have any generally useful skills, they should be able to serve their country. Oh don't worry they can sure try to find something for you to do.
The biggest problem I see with this argument is people generally associate the draft automatically with duty on the front lines. That is not always the case however. If you are proven or suspected to be unfit for it but are still of use for them, they could stick you in somewhere like cleaning, cooking, mechanics, etc. The military and their establishments function like their own little town on a base of any kind. Now would I be supporting women for front line duty? Personally I'm against it unless they're proven otherwise, because historically men have been the warriors and women have been in the clerical roles and it hardly should change here.
Actually, in retort to someone's "mandatory service" comment, I would definitely support a system where 18 year olds automatically serve their country for 4 years. I believe Mael could also back me up here, because the military teaches you more than how to shoot a gun. You learn survival, discipline, combat, and a slew of other useful skills depending on your M.O (where you work). It would discourage general laziness, educate and sharpen the populace, and maybe give people a potential path to go after the mandatory 4 years in over. Plus in America, the benefits for retired and active servicemen is amazing. Particularly free healthcare (that's a HUGE game changer when you'll never have to pay much for hospital bills and other med shit).
Also, to put it in perspective, here's another little quote.
"You wanna live in the land of the free and the home of the brave, but the brave can't be free if the land isn't home and that land won't be home so long as folks out there want to take that American flag and shove it so far up your anus that you crap stars and stripes for a week, and as you're sitting there on the toilet with the star spangled Moctezuma's Revenge (real bad diarrhea travelers get) there's one thing I can guarantee, you won't care then..."

Basically unless your homeland has regally screwed you beyond all recognition, you should serve in the military when you are called to arms. It's an innate human instinct to protect all that you have worked for.
