We live in a globalised technocracy where people have been reduced to nothing more than economic units. Voting legitimises an illegitimate system. Don't go out to vote in their little charade. Have some dignity. Don't contribute to the tryanny of modern governance systems.
Of course, no system is perfect and voting is not inherently good or bad as it has its challenges but it's actually a vital instrument for shaping our collective Future. I understand the point you are trying to proof but what if we all decide to stop going out to vote, then what next? Isn't it denying ourselves the right/chance to at least try to make a choice or try to make our voices heard? What if your vote is that one last "key" we need in choosing a good leadership for the system, Never say Never my friend. Participating or voting in a system that seems flawed may feel like legitimizing it but don't forget that abstaining from voting may not also be the most effective way to bring the change we desire.
