I agree with that "in a vacuum," so to speak, but we're not operating in a vacuum. The ideology that promotes women's eligibility for a draft is the same ideology that is demanding that women have military roles identical to men's.
Now take a sailor who has been on a destroyer for the last 4 years with a CO and XO who were far from pleasant to work for (psycho perhaps). The ship was deployed at sea for two of those for years. The ship was under manned so even in port he was on the ship one out of three days. So basically this sailor spent 3 out of the last 4 years in a metal smelly metal box being tossed around the ocean like a cork half the time. Conditions are not much better than a convict in prison.
Ok, now his TOD is up and its off to shore duty? Hurrah! Maybe supply depot in Hawaii? Maybe teach at a Navy school in FLA? Well bad news sailor all those jobs have females now. So your choice is another G-D destroyer for 4 years or quit. Sucks.
You do realize that the biggest push for women in combat roles are coming from women in the service, mainly officers, who feel that they are being overlooked for promotion because they lack combat experience.
