The pirates, by and large angry white (young) men, advance primarily a negative concept of freedom (no surveillance, no copyright) in service of strong, productive individuals. Based on this atomistic view of freedom they envision organic communities of the like-minded. A kind of American-style libertarianism.
In certain contexts, like the volunteer communities of the internet, this can be a progressive position, but extended to society at large, it takes on a strong right-wing character. Because it has no sense of solidarity expect for peers, which are thought of as a select group. As long as there is infinite space to multiply the groups, as there is on-line, this is less of a problem, but off-line, this turns into exclusion.
