They lost me with the first word in the title--"communitarianism" being simply another alias for Communism. The TRUE agenda (Communism) having been pretty much discredited by the completely vicious and inhumane treatments of their own citizens, the advocates of Communist ideas now find it necessary to re-invent themselves under another name.
It is no surprise that "citizen (aka "domestic) disarmament" is high on the agenda, as failure to do so might result in resistance of said citizens when the government jack-booted goons come to arrest, torture, and/or kill them.
