My great grandparents emigrated from a little Jewish community just outside of Kiev to Saskatchewan in 1895. Even back then it wasn't a great idea to be a Jew in Ukraine. Although rather poor, they still left whatever they had to leave Ukraine and come to a safer place without any real knowledge of what to expect when they arrived.
One of my great-grandfathers found Saskatchewan to be not conducive to his religious orthodoxy, and went back to Ukraine, where he was promptly murdered by Ukrainians a year later.
Growing up in Winnipeg I soon found out that Poles and Ukrainians were very anti-semitic. When I first moved to Montreal in 1972, and saw young Jewish men wearing Stars Of Davids and Chais openly I thought to myself "you guys are gonna get killed", until I discovered that anti-semitism among the French was much more hidden and subtle.
Anti-Semitism has deep roots in Eastern Europe and Ukraine.
If anybody had told my great-grandparents that Ukraine would someday have a Jewish President, they would have thought that person was out of his or her mind!
