I'm not attacking deontology. Or consequentialism.
I'm a bit confused as to why we're arguing when you haven't actually said anything I disagree with since your first response, so I am going to guess that what has happened here is that because I formatted my original comment as "here is the argument for why voting is bad", "here is the counter-argument for why it isn't", it comes across as me thinking that the counter-argument is a refutation. That's not my position. I was not trying to state a position. I was merely trying to put forward my analysis of why there is debate by offering the arguments I commonly see both for and against, and I put the "against voting" arguments first because that most directly answers the question I was responding to.
I think we both agree that there is no correct answer to the trolley problem beyond what is correct to you personally, and I think we both agree that there is no correct answer as to whether you should vote beyond what is correct to you personally. That is why I think the trolley problem is relevant.
FWIW I think that my "I will not vote for Labour" stance demonstrates that I at least lean more toward the deontological position (in this case, at least), but in truth I couldn't honestly tell you that I've come to a firm moral decision. If the Tories and Reform have some fresh new lunatics in charge come the next election I may well be scared enough to change my mind.
