Well, if you're going to go by dictionary definitions, then by every definition listed ancient Athens counts for some definitions of 'people'. And for some definitions of 'people', the USA is not a democracy in any way listed on the link below.

Basically, dictionaries are useless. All they can do is give a meaning. People have written entire 300-page volumes defining just ten words. Attempting to define something as nebulous a 'democracy' by referencing a dictionary is an exercise in futility.
