>The document doesn't grant me the right to life.
Nothing does. You don't have an objective right to life.
>Everyone has natural rights.
There is no such thing as a natural right.
Natural right implies that it is a objective right, something that can be reasoned to be always true no matter the mindset of those who reason.
Human rights or just about all rights we have are subjective, we made them up.
And yes, that includes all basic human rights. Your right not to be violently murdered is at it's essence a subjective notion that you don't want to be murdered above all.
It's true that some documents have documented these rights, notably the declaration of independence and some other similar. But that doesn't change the subjectivity of these documents either.
>You don't have the right to take anything from me just because there's another person in the room.
Again, this is entirely subjective. The other two people in the room might massively disagree and argue that since their are in the majority, they have every right to do what they want with you and your property.
It entirely depends on the moral and ethical framework used by those in the room.
For some, it might be fully ethical to murder you and practice their cannibalism a bit.
>The state doesn't get special moral or justice exemptions just because it's a special type of group.
Which is just as subjective.
Most people in the US seem to agree that the moral framework they have constructed is beneficial to them and that a majority rule is sufficiently moral and ethical to ignore the complaints of the few.
You can whine about it all day but it doesn't change that the majority believes that a majority can rule (which is an entirely subjective notion).
