On the contrary, ma'am.
The German state never had an institutionalized, systematized, fully legal system of buying and selling slaves, oppression, discrimination, and bigotry against Jews that America has had against blacks.
Certainly, after Napoleon's defeat, the pogroms and riots against Jewish families and businesses and the limiting of rights and job availability, etc., to Jews in certain parts of Germany flared up. However, that resulted in up to 70% of Jews in Germany emigrating to America and other places where they felt they would be treated fairly. Black slaves in America never had that chance. If slaves were lucky enough to escape, slaveowners pursued them and were protected by the government in doing so.
Earlier in history (the millenium-period you speak of), the Roman Catholic Church (then styling itself "the Holy Roman Empire") began levying taxes against Jews (whether myth or fact, they believed the Jews to be wealthier than others). As they did later in history, Jews began to leave the areas where they were afflicted and, ironically, the governments backed by the Catholic Church, began to invite them back.
And of course there were the Crusades during which thousands of Jews were massacred and persecuted. But neither the Crusades, nor Jewish persecution by the Catholic Church is unique to Germany.
The point I am making in my article (apparently, not well enough) is that America's racism and bigotry and prejudice is too deeply engrained into the bedrock of our nation. The argument that, 'Hey, look what Germany did after Hitler and the Nazis' is far too simplistic to be applied to our crisis.
