You emotionally dislike the fact that voting is irrational, so you've downvoted this post, but you haven't even attempted to reason with me.

If this post is getting downvoted, it's probably because it shows a lack of awareness of a zillion previous discussions on voting, e.g. this one. Many LWers like the decision theory called Timeless Decision Theory, in which - if I understand it correctly, a dubious assumption - you consider yourself to be making a decision not just for yourself, but for all similar minds. One advantage of this is that TDT agents cooperate on Prisoner's Dilemmas. Some people consider voting to be an instance where TDT agents decide to vote.

Your comment complaining about being downvoted was downvoted for complaining about being downvoted, and for making a probably-inaccurate accusation about why.
