Similarly, I will often downvote comments that complain about being downvoted, either as a reply or an edit. I find whining about votes detracts from the discussion and has no place here and therefore is worth a downvote. People need to become less concerned about their scores - if people find a comment is valuable, it will be upvoted. If not, it may be downvoted and complaining about being downvoted makes it less valuable, not more.

Of course, by my own logic, this comment should also be downvoted purely because it is a meta comment, is off-topic and detracts from the actual discussion. Hell, if I could, I'd do it myself ;-)
