The typical Lockeian reasoning for the Illegality (notice it’s capitalized, you’ll see why) of the Draft goes something like this.
Natural Law and Natural Rights are the foundation of Lockeian philisophy. Under these, people have the Right to Life, Liberty, and Property: The Three Basic Rights. Now, no one has Right to deprive you of your Three Basic Rights. Depriving you of Property is Theft. Depriving you of Life is Murder. Depriving you of Liberty is Slavery. These Rights are given to us not by the government, not by the people, but by something higher, whether that be God, some Deist entity, or blah (I have no idea what the something higher is under Atheist Lockeian beliefs).
Now, that said, it must be reiterated that no one has a Right to your Life, Liberty, or Property. You can voluntarily allow them to use or take your Property through sharing or exchange of money. You can voluntarily enter into the service of someone else such as a volunteer army. You can voluntarily choose not to exercise your Liberty (think people sometimes censoring themselves at work).
Now, we’ll go with the Right to Life and Liberty parts. As said, you can voluntarily choose to enlist. In ways, you are volunteering to give up your Liberty to enter into the service of another. In addition, no one has the right to tell you to forfeit your Life. No one has the right to require you to lay down your Life if you had not already volunteered it. The Draft takes away your Right to Liberty. It requires you to enter into the service of others unvoluntarily. You have now become a Slave of the Government. Drafted individuals are also forced to give up their Right to Life. They are forced to die and to kill for causes they may not actually believe in. The Government has now unlawfully Murdered you.
Now, you might say “Well, volunteers for the military don’t always believe in the causes they’re fighting for!” That’s true. However, they did volunteer. They did enter into a contract wherein they agreed to waive the exercise of some of these Rights. If we enter into a war they do not agree with, they can fight until they’re term of duty is up and may choose to no longer volunteer. They may also choose to desert their post, in which case they can and probably will face military punishment (I believe the standard now is a year in jail and dishonorable discharge. Info might know).
That said, I will never be drafted. If there was a war such as WWII that I truly felt deserved being fought in, one that I was personally touched by, I would volunteer. I’m not as morally opposed to Iraq as many of the people here, but I will refuse to fight in that desert if I were drafted. I will fight to end the draft. I will fight to overthrow the government that does respect my Natural Rights. I will exercise my Right, MY RIGHT MY DUTY, to create a government based on Rights, on Freedom, on Liberty.
As of now, I fear both parties. I do not trust the Republicans or the Democrats. They are both corrupted with power and filled with hatred towards Freedom. They both claim to support Freedom while the other party hates it. They feed us tidbits of “freedom” that is oh-so mercifully granted to us by our Lord and Master the Government. All the while they are stealing from us, enslaving us, and murdering us. I refuse to support those parties that believe government must be strong to do good. I will and, for the forseeable future, always will vote Freedom First. I’m proud to be a Libertarian.
