In other words, the "confederate" social movement is not always anti-central-government! It is only opposed to federal government when it does not control those levers of power. Witness the tepidness of anti-government proclamations during the tenure of GW Bush. Indeed, it is a wrathful unwillingness to let the electoral winners have their legitimate turn that was behind the hysterical reaction to Lincoln's election... and (one might argue) Obama's.
