In general, I agree with that principle. However, egregiously stupid downmodding is damaging to the discussion. I wouldn't have started this thread over a post that clearly deserved to be downmodded; I'd just be embarrassing myself by drawing more attention to the post.
The YouTube link comment deserved the downvotes. You meant "as a renter I'm very happy about the lower rents". But directing people to listen to videogame music, at another site, to get your meaning adds a level of frivolous, time-wasting indirection. It's understandable people didn't appreciate it.
i haven't downvote anything in the past year or so because it stiffles my creativity ... downvoter role fits the admin-type ... you know, the uncreative ones
don't bother explaining, argue with an idiot, you become one ... argue with uncreative, you become boring
Resist complaining about being downmodded. It never does any good, and it makes boring reading.
