Democracy only works if people actively participate and make their voices heard. Not voting, campaigning, etc. only leads to further entrenchment of the lobbyist nightmare.
Further, rejecting democracy because "your side lost" is idiotic. When your side loses in a democracy, you get to try again in however many years when hopefully your side's arguments bear out in the negative impact of actions of the other side. When your side loses in a military dictatorship, if you try again, you go to jail.
