In fact you do not have a right not to vote in democracy as created by the ancient Greeks. According to them not caring caused you to lose your civil rights.

A fun trivia is that the word idiot (Ιδιώτης - private party) means the person that does not care to take part in public affairs and was an insult in ancient Greece. Now in Modern Greek it is no longer insulting, but the insulting meaning found it's way through Latin into English.

Aside from the history trivia though I agree that in a community like m.org you have every right not to vote.
