What can we as humans do to help alleviate antisemitism in areas of eastern Ukraine now in revolt against Kiev?

This news makes me greatly heartsick. The Jewish citizens in the city of Donetsk have been ordered by some authority to register themselves and declare all their possessions. It honestly horrifies me.

I personally have a difficult time understanding hate.

Are there steps we as thinking, acting human beings can take wherever we are to help our fellow humans who are suffering under this fearful tyranny?
