Society should abolish age-based voter eligibility criteria, which are arbitrarily discriminatory. Voting rights comprise the formal mechanism by which citizens freely criticize, and remove from power, their governments. To prevent a subpopulation of citizens from exercising those rights, based on a morally irrelevant age-based criterion, is straightforwardly to oppress that subpopulation. All that should be required for a person to vote is for that person, regardless of his age, to willfully write or dictate a statement before the law proclaiming his desire to do so. This measure would open the vote to all desiring citizens while oppressing no one . It would increase the diversity and the creativity of the criticisms behind the votes cast within our society, and it would make society more free, both of which could help to make our society more rational.
