The concerted effort within the "Liberty movement" to divorce the concepts of property and ownership through deconstruction of flawed Lockean property norms is prima-facie evidence of post-modernist infiltration.
Property and ownership are interdependent concepts that are meaningless when separated. By insisting that "self-ownership" means something other than having the highest claim to one's own body in the event of a physical conflict over its use, post-modernists hope to define exclusion, discrimination, and mean words as immoral acts of trespass for which physical retaliation is justified.
By allowing them to present the provocation of physical conflicts with anyone they deem to be a racist, Nazi, xenophobic bigot as acts of defense, the ethical standard they propose renders the concepts of ethics and property -- and even logic itself -- entirely meaningless.
Donny: "Are these the Nazis, Walter?"
Walter: "No, Donny. These men are nihilists, and there's nothing to be afraid of."
