There is absolutely no reason or excuse not to vote.  It's not the fact that you don't vote that's the problem, it's the fact that this is the prevailing attitude, and that it's attitude held with some malformed sense of pride.  How do you think the elections are so easy to influence?  Because most citizens simply don't vote.  The democratic process is shit because we have failed it, we have let it go to shit out of apathy and cynicism; not to say that it's ever necessarily been an adequate mode of government, but how the hell would we know if we don't even take advantage of it.  Voting is not an admission to conformity or adherence to propaganda, not voting is more-so if the statistics are of any consequence.

If you really don't feel that you influence the outcome, at least throw your vote in with a third party and add to their numbers.

Sorry Jorkest, this isn't an attack on you.  It's a much larger problem than that, but it does require an individual sense of responsibility.  We are being absolutely crushed by the forces of nihilism and the post-modern void, because it's simply easier and more comfortable that way.
