I see that I have received seven downvotes, so clearly I am a worse person than you are, so you should feel better about yourself.
Okay, seriously now, if you are taking downvotes (or upvotes, for that matter) personally, then you are doing it wrong. Or at least partly wrong. Because people like me don't vote on people, we vote on ideas.
If I give an upvote on a post, it means "I like this idea", or "I agree", or "You have expressed this very well" or something along those lines. An upvote from me does not ever express the meaning "I think you are a good person", still less "How about dinner and a movie?"
Similarly, if I give a downvote on a post (which WikiTree claims I have never done, but I'm pretty sure that I have at least once, so I'm giving WikiTree a downvote on this issue ;-) ), it means "I don't like this idea", or "I disagree", or "You could have expressed this better" or something like that. A downvote from me never expresses the meaning "I think you are a bad person", nor "You are getting a lump of coal in your stocking this year". (In fact, there are people on WikiTree whom I have come to like a lot, but I don't necessarily agree with everything they say.)
Now, granted, not everybody thinks like me (now that would be a scary thought...) but you should allow for the possibility that, quite apart from people hitting the downvote button by mistake, at least some of your downvotes are due to people disagreeing with a particular idea (or at least the way you expressed it), rather than not liking you as a person.
But even then, people on WikiTree are pretty easy markers. With all the ideas I post here, only 7 downvotes is a really astoundingly small total. (Unless all the people who think my ideas are crazy are just hoping that, if they ignore me hard enough, I'll go away.) If I ever had marks in school that were as high as the proportion of my upvotes to my downvotes, I'd actually be smart!
