Wikipedia is not democratic, and certainly not in the sense of a majority (vote). It is governed by a feudal model where there are lords and vassals, and you are the peasant.

Actually democracy is not necessarily a rule of majority, it is a system where everybody has equal access to power. There are several models how this in practice can lead to even minority deciding. Also, the majority can change ad hoc, depending on the issue being decided, it is not fixed.
