The word "voting", since it includes both electoral politics and signifying one's preference for a certain resolution, seems rather vague. Etymologically it comes from "a vow to do something", even more vague.
Reasons I wouldn't vote (mostly in elections):
-Futility. Trying to elect a ruler in any system competent enough to gain a monopoly probably would not fundamentally challenge that system.
-Distraction. I would not desire to empower an elite at the expense of everyday people. I want people to have free agency, not coercive power. Empowering one sector of a population at the expense of everyone else would only at best distract me from actualizing anarchic relationships or demolishing hierarchical ones. Example: guerilla gardening, Food Not Bombs, and Black Panther food distribution offer useful examples of autonomy from the welfare state.
-Insufficiency. I can understand, and feel for, people voting in elections out of a perspective of self-preservation, or against their own enslavement. For example, a womyn trying to elect a politician who opposes the criminalization of abortion, or a man trying to elect a politician that opposes military conscription. At the same time, bandaids do not cure diseases, and shuffling a deck or changing the deck's players does not change the cards.
-Competition. Representative democracy/aristocracy institutionalizes competing factions, with all of the pitfalls of politics in place.
-Bureaucracy. Mass organizations tend towards sluggishness, and other hindrances.
-More futility. Even if I voted for someone to introduce systemic instability in furtherance of revolutionary conditions, that one vote would still count as much as a drop in an ocean with today's population sizes and the notion of "one person, one vote".
-Incompatibility. Representation relies on reduction and substitution, and always diminishes the represented. By necessity political representation filters out aspects and experiences, especially when politics removes representatives from the community/context they *supposedly* represent.
-Inconsistency. I would not willingly compromise certain convictions, namely, anti-authoritarianism.
So when would I vote? If it seemed effective, empowering, sufficient, non-oppressive, non-exploitative, direct, compatible and consistent with my principles, I would. I would vote to abolish a law if I felt my single vote had a chance of changing the outcome. I would probably also vote under duress. And I vote in consensus decisions, formally and informally, quite often.
