Downvoting

Some members will remember a controversy some time ago about the introduction of the "downvote". Most members who commented were opposed, some very strongly, but the management ignored us, as usual. I have just been downvoted, for the first time. I found it an unpleasant and offensive experience. I suppose it could have been a mistake, but if it wasn't, I challenge the person who did it to have the courage to explain what he or she disliked about my comment.
