Democracy is not a one size fits all kind of concept. There are many kinds of democracy. There are Monarchical Democracies, Parliamentary Democracies and even Imperial Democracies such as the Japanese. Since 1999 we also have a Bolivarian Democracy. All of these democracies though share one same characteristic; they are all Republican Constitutional Democracies.
In a lighter note you could say that they are different kinds of “Arepas” (Reina Pepiada, Carne Mechada, Queso de Mano, etc.) but they are all “Arepas”.
There are also Popular Democracies (Cuba) and I would even venture and say that we now have what could be considered Religious Democracies such as Iran. They also hold elections but they are completely different systems of government.
These democracies are not “Arepas”; they are “Tortillas”; and, while both are made of corn flour, millions of Mexicans and Venezuelans can attest to the fact that they are absolutely different.
