i'd say morality IS objective and it depends upon private property rights. Don't violate the rights of others. We all have the universal ability to understand aggression against our property either personal or other. None of us like to be stolen from for example, even thieves themselves.
Also disagreeing with your premise doesn't in any way reaffirm your argument... from what I can see anyways :)
I'd say you need to open more books besides libertarian ones.
What you perceive as "rights of others" are different from culture to culture. For example muslims have agreed that they have a right to stone someone that sins. Is their right. they have books and agreements about it.
No we don't all have the universal ability to undertand aggresion since every piece of land you see around you, including your own has been violently conquered. All land, all private property is stolen from someone else.
I don't see you doing any argument. Look man, having a nickname that represents an ideology is not the best way to go if you want to see the world as it really is. i see your point but also do re-examine your premises :)
I am a voluntaryist myself but i know the limitations of what i believe.
