So your claim is that all people ought not be aggressive.
No, my claim is the same one that the Non-aggression Principle makes: that no person has the right to be aggressive. The functional result is that all people ought not be aggressive, but all I am claiming is that no person, or group of persons, no matter how they are constituted or their decisions are made, have the right to.
ok but for it to be universal this statement must be either objectively valid and not a product of your personal preference or agreed upon by everyone in the universe. since we can rule out the latter, inorder for it to be objectively valid it must be logically deducible. how does one logically deduce that no person hast the right to be aggressive?
Because any right, in order to be a right, must be universal. Therefore, either everyone has a right to be aggressive, or nobody has. With me so far?
ok sure you can define any word you like any way you like for the sake of this discussion lets define rights in such a manner that they necessarily apply to everyone, no harm in that at all.
Good, because that's the definition that the dictionary uses, too.
Now, as to the origin, there are several ways to look at it: Rights could come from:
1) An inherent nature of the human condition, such as is often used to justify self-ownership: You have the first, best claim on your body, therefore you own it.
2) An external creator, with a higher authority than all others, such as the founders of the United States used to explain their conception of rights: that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness. or
3) An agreement, which must be reciprocal in nature, that both participants in an interaction have a certain right, and thus it should be respected: By not killing someone, you are acknowledging their right to life, and therefore, your right to life is respected as well.
Note that all three of these require that a right, in order to be considered a right, must be universal: Everyone here has the original claim to their body, as we're all human (I assume). Everyone has the same Creator, or they don't. If you deny a right, then you can not claim it for yourself... the murderer can hardly expect to have his right to life respected, after denying the right to life by killing someone.
But this is all just a side-track. You've already agreed that rights need to be universal, regardless of their origin. So, if anyone has the right to aggress, then everyone does. The state, however, disagrees. They pass multiple laws which indicate that people do not have right to aggress: laws against rape, murder, theft, etc. But then they empower agents to do just that: rape, murder, and steal. So, are they violating the criminals' rights, or ours?
