I know everyone is entitled to their own opinions and voting on Questions and Answers is a private thing - but my understanding on the casting of Up and Down votes on Main is supposed to be with regards to how well a Question is posed and how well an Answer addresses the Question (with documentation) - correct? Up and Down votes aren't supposed to be the Facebook equivalent of personal Likes and Dislikes - correct? Those are my assumptions, which lead me to my question here.
In response to the Question Did the Soviet Union hand over thousands of Jews to the Nazis in the spirit of the Molotov–Ribbentrop Pact? I offered this Answer and received three down votes (thus far) which I interpret to mean three voters see something technically wrong or unhelpful with my answer. I reviewed the Meta Question on Why Did My Question Get a Downvote (which doesn't really address Answers, but looking for clues anyway) and Why did my answer get a downvote? - so far I'm stuck with no guidance on what to do to improve.
Can anyone offer suggestions on how my Answer can be improved?
