Encouraging people to explain down-votes
"Above all, be honest. If you see misinformation, vote it down. Add comments indicating what, specifically, is wrong. Provide better answers of your own. Best of all — edit and improve the existing questions and answers!"

Alright, my question about this "Be honest" item is, why is it not enforced that a down-vote requires a comment?
There have been questions I have answered - and I'm not one of the long time users - where I know for a fact that my answer was more concise and more to the point than those of others. Then I get a down-vote, but there is no clue for me as to what I did wrong.
Was I impolite? Did someone misunderstand a sentence? ... dozens of possibilities and no clue whatsoever. Asking in a comment to my answer will be pointless, too, because no one but other commenters will receive a notification about my comment. And it could have been some random person down-voting.
Thanks for reading. Now let's discuss :)
Edit 3: the topic seems to spark a heated discussion at least, even if that results in down-votes for me. I'd just like to include this link to "Encouraging people to explain down-votes" which jzd (see comment section) came up with. This one was not suggested when I wrote my question, but it fits exactly what I wanted to ask even though my choice of words was perhaps not as elaborate.
