What do you think of as a ‘citizen’? A citizen has to be more than merely a ‘responsible voter.’ So, here is my vision of a citizen. A nonpartisan citizenry is capable of understanding the core ideas of their republic. Additionally, such a person would be able to detect fallacious reasoning and calmly question the partisan lines.
Such a citizenry would be able to take a step back, consider the different dimensions of a given policy, and examine these ideas, with and against the parties.
Such a person would be able to criticize both the Republican and Democratic parties. If one supports a given party, then this is a decision based on many factors. The sole factor, however, should not be from a kind of tribalism, that it is your party. Presumably, if it is your party, it is your party because it stands for something that you genuinely endorse.
Further, such virtues as this would be regarded as a common discipline. A free people can reach agreements through rational inquiry and nonviolent cooperation.
See my other articles about voting, social media, and logic, so that this bare vision is fleshed out a bit more. These stand as starting points for the philosophical ideas in practice. There must be something common to our community if we are above superficial divisions of race, sex, religion, and partisanship. Without which there is just the barbaric struggle of will, might, and force.
