It would appear Congress is going to pass a law requiring females to register with the Selective Service so that they can be forced into involuntary service in order to do violence on behalf of those who forced them into involuntary service. There is bipartisan support for this insanely immoral practice and ironically some float the justification that a draft would equally pull people from all walks of American life and throw them into the thresher of war, which would then prevent war because it would touch the lives of more Americans.
Or to put it more succinctly, the argument is that government violence forcing people to inflict government violence will prevent government violence.
Regardless of the justifications for or against the draft's involuntary service, the reality is that it's just plain ole unlawful via our Constitution. Full stop. The Thirteenth Amendment states:
Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction.
Of course Americans have extremely little concern for their constitutional rights, so pointing out that government is doing something unlawful is met with a collective yawn.
Land of the free. Where people are forced through threat of government violence to go inflict violence, because the war isn't so obviously in America's interests that people would sign up to defend those interests voluntarily.
