The locus of right wing unity (between Libertarians and Conservatives) is the UnproblematicAcceptanceOfTheSovereignIndividual.
In fact, some times the right's appeal to personal responsibility is just a denial of the same concept. "I screwed someone with my actions/decissions but in fact was his fault because he didn't that or did so. It is not my bussiness".
For me the right's "Personal Responsibility" is in many cases just self-delusion.
