USC Title 10, Sec. 311 says, in part, "The militia of the United States consists of all able-bodied males at least 17 years of age and, except as provided in section 313 of title 32, under 45 years of age who are, or who have made a declaration of intention to become, citizens of the United States and of female citizens of the United States who are members of the National Guard."
Article XV, Section 1 of the Utah Constitution says, "The militia shall consist of all able-bodied male inhabitants of the State, between the ages of eighteen and forty-five years, except such as are exempted by law."
The problem is that we evolved to using a large standing armed force -- especially since the war between the States. The militia has largely become an object of disdain. The Army Clause of the US Constitution points to the notion that a large armed force shouldn't be necessary for periods loner than two years -- only during periods of national emergency.
Among other problems, our large standing armed force enables politicians to easily stick their noses into the affairs of other nations where and when it is none of our business. The draft becomes evil only when it supplements that large standing armed force.
If those who abhor the draft (and/or the large standing armed force) would push for phasing out the standing army combined with the full restoration of a well-regulated (ie established, equipped, and trained by each individual state) militia and then actively pursue their own duties in the militia the draft would forever be a distant memory. However, I suspect that many of those who most vocally reject the draft would also be the least likely among us to accept their militia duties (hence the justification for a draft). They are self-righteous pontificating cowards. You know who you are.
