Depending on how you feel, questioning whether we live in a democracy is either incredibly stupid or incredibly scary. In a democracy, every member who is eligible helps to decide how they are governed. Essentially everyone has the same voting power, the same level of influence over government, and the same means of expressing that influence.
But in reality this is an idealised version of democracy. In truth, we admit that there simply isn’t time for us to all have a say in every matter that affects us. Instead we elect officials who more or less represent what we want; accepting that they may stand for a few policies that we don’t agree with but we take the rough with the smooth. After all, the nature of democracy means one doesn’t get their choice every time. It’s the nation’s consensus.
