Yeah I get how downvotes affect people and myself at times, you try to think extra hard to make them personal and try to ignore that maybe it wasn't. It's not a nice thing to do and receive as @slobberchops put it in his comment above. I think seeing who gave the downvote, what kind of downvotes they usually give and if they maybe left a comment in either your post or on another post they downvoted helps realizing that maybe it wasn't personal and maybe they aren't aware of certain things.
Like when I leave someone a downvote, which happens seldom, I try to leave a comment. If the user let's me know that "oh okay but this is the first post in forever I've gotten big votes on" or something that may make me re-consider then I will. What I despise is people who instantly go on the offensive, say things like "this is censorship", "hive sucks and this will kill it", etc, then I know it's probably that they just care about maximizing rewards and are doing anything they can to get that to continue which won't go well from my point of reconsideration.
