Not “might”. Will. And voting is absolutely not tantamount to telling other people how to live their lives, it is rather a statement on the way you think things should be run. You have a right to that, because we live in a society together. If you think you can go be a hyperindividualist all by yourself, you will most likely die early, but more importantly you will never enrich anyone else’s life, or have your own enriched by others. We’re all individuals, but we are part of a greater whole.
And just to play this angle: if you won’t vote because you “won’t tell others how to live”, then you would equally stand by and let the evil harm the helpless, for the same reason. Get off your fence and stand for something.
