Wait! Government founded, managed, and operated socialism is...
Communism
So... really our national parks, military, and police are communist, not socialist.
An efficient argument in regards to what is and is not "socialist" or "communist" truly relies on the system of government it exists and functions under. In other words, are the limitations of these otherwise "socialist/communist" ideals kept in check by any documented principle? It seems then what we're really discussing here is the difference between a Republic, a Democracy... or something else entirely.
All systems of government have facets of them that could be considered socialist or communist. I asked for examples of systems that are
all one or
all the other and there was no response. Why? Because there are no examples. The question becomes then, how are those powers or ideals limited? When you have a socialist ideal, entity, movement, legislation, etc... that increases in scope without clear limitations outlined in the founding document of a Republic, you have something that begins to look more like a Social Democracy or something else entirely. When people rail against "socialism", they are not being somehow inconsistent as all systems of government have provisions that intertwine with socialist/communist ideals and because the activity in question is not clearly limited in scope; unlike the police, military, and national parks.
Simply put, when people rail against
socialism, they are not railing against facets of nature that exist in all systems of governance. They are railing against economic policy increasingly hostile to capitalism and free enterprise.
So... you can call something "socialist" or "communist", but to do so without acknowledging the system of government these natures exist and function under is lame.
