Why not debate its rightness or wrongness. I’ll go first. Not only is the draft wrong, it is illegal. Not only is there no delegated draft power, but it is not necessary for any other power and violates the ban on involuntary servitude.
Go ahead and debate it. I’m not going to.
The SCOTUS has already ruled at least a few times on the constitutionality of the military draft, and its conclusions differ from yours. They held that the draft was constitutional under the "necessary and proper" clause in that it was deemed necessary and proper in order for Congress to fulfill its constitutional power to raise an army and navy and other military services. That power superseded any Thirteenth Amendment consideration of involuntary servitude because, according to the SCOTUS, it was in the original Constitution and was not explicitly overridden by the Amendment.
I don't necessarily disagree with the argument that a military draft is involuntary servitude, but merely point out that there is already established constitutional law on this question.
