Democracy is a good thing. This seems to be common sense today. But nobody can really answer, what that is, democracy? Even though of course there are many answers, like always when nobody knows the answer. A closer look on these answers shows that most of them can be reduced to one and the same answer: Democracy is when you elect your president.
However, even in the German Democratic Republic people went to vote (in the socalled Volksdemokratie) and whether states like Russia are very democratic although they have elections is doubtful. So either democracy is not only about having elections or it is not necessarily a good thing when it is reduced to electing a president.
Let’s go back to the meaning of the word democracy: The demos rules. Who is the demos: the expression was used to describe the non-noble citizens of Athens. Taking this at its word (unfortunately in history it was never taken at its word) must mean that citizenship is not inherited. But if it is not inherited, it must be possible to achieve access to the demos by demanding or fighting for a position within the demos, because any criteria of citizenship can be democratically challenged. The demos then can never be fixed to one closed group, but has to be ever changing.
When demos rules one should in the best case never know in advance, who is ruling, because any development of a ruling class, installs back again a fixed group, which is incompatible with the demos as being open to newcomers.
Allowing real demos that means a political subject, which is ever changing, can be frightening. Immigrants can then legitimately demand to become part of the demos. The demos is the legitimisation to ask for participation in it.
I am not so sure whether this is what people have in mind when they say: democracy is a good thing.
