Re: democracy is a concept
We don't have a free electoral system.
There are it must be admitted varying degrees of freedom between electoral systems. Here in the Land of Under we are fined if we don't vote. I believe that in UKLand and USia that one is free (as I am not) to choose whether or not to vote. In all three places, we are free to vote for whichever party/candidate we choose. Some states have but a single party. Since you do not state under which system you live, I have no way to evaluate your statement.
Despite my lack of freedom as whether I vote, I do not feel at all unfree since I can vote for whoever I wish among the sometimes bewildering number of candidates, or cast an informal vote if I choose to do so.
