I don't concern myself too much, the value of votes are zero anyway, and the value of people who down vote is zero as well as far as I'm concerned. I have never down voted anything another person has written, I just think it's base behaviour.

You have at least one insignificant person on your side. I similarly almost never downvote. But they disabled my voting ability because I upvoted too generously.

There are many cruel and pugnacious creatures here.

Indeed, it's best to remain indifferent, lest... behavioral modification ensue, and one become strange.
