Well, I have a pretty strong understanding.
Communism,Socialism,Capitalism = economic model
Democracy, Monarchy, Oligarchy, Authoritarian = power model
Any economic model can be used along with any power model.
Not sure what you were trying to point out with that statement. I imagine you are assuming because many of these posters do not agree with socialism that means they assume it is always undemocratic.
Enough of this. I think the OP had a good point, it was made and I'll not waste any more time on this elementary political debate.
