What exactly is libertarian socialism? It seems that there are very few libertarian socialist politicians, so it is difficult to find the policies that libertarian socialists might support. I understand that libertarian socialism is a very broad philosophy, but what exactly distinguishes it from state socialism? Is direct democracy the major difference? Must a socialist be either a libertarian socialist or a state socialist? I would appreciate if this discussion could remain about the philosophy itself rather than the arguments for or against socialism in general. Thanks.
