To the contrary.

Jürgen Habermas, a highly influential philosopher, have argued the value of a public debate as essential to a democracy. A society that begun to lose its public sphere have begun losing it's democracy. When elections become routine, when only media or elected politicians present the issues and represent the only debates that are heard, when forums for people communicating with eachother are closed down, democracy is dying.

The argument that a person forfeit their right to complain by not voting isn't democratic. It's in fact a directly anti-democratic sentiment.

The capacity to speak out, both in being free to speak and having the tools to speak, are the building blocks for a democratic society. Not adherence to social systems or bureaucracy.
