alt Hacker News> My decision to vote is not rational
And I think this is great. Often our convictions aren't, and those are what make us interesting! I also think it's interesting how/why we rationalize our irrational behaviors! For example, I generally feel the same way as you about voting, but I don't like living as (in my mind, at least) a defeatist. Also, I feel that if I didn't vote then I have no right to complain or have an opinion about the things I didn't vote on. So I go vote for those reasons.
I mean, I do actually vote in every election, for the same reasons you are talking about. There are social reasons I do it, and there is something communal and bonding about the process of elections.
But it isn't because my individual vote actually matters.
