Q: 'Does the idea that "given that all decisions are a form of action, and that votes, when made conscientiously, represent our values, then every choice is a reaffirmation of our values" sound nothing like existentialism?'
A: 'The idea that you proposed does indeed align with some aspects of existentialist philosophy, which emphasizes the individual, the subjective, and the importance of personal freedom and choice.
Existentialism posits that life has no inherent meaning, and it's up to each individual to create their own purpose or essence. This philosophy emphasizes the act of decision-making and the consequences that come with it. In this light, your statement that "all decisions are a form of action" and that these choices reflect our values is consistent with the existentialist view that we create meaning through our actions and choices.
Moreover, the existentialist emphasis on authenticity—living in accordance with one's true self and values—also resonates with the idea that conscientious voting is a reaffirmation of our values.'
In philosophy everything can be anything else if you muddy the waters enough.
Concept of choices as actions reaffirming values doesn't sound like existentialism, if only because it's simple and clearly stated while existentialism has things like that to say about choices: https://plato.stanford.edu/entries/existentialism/#AnxiChoi
