That is a Nazi expression. The Nazis called Germans who defended Jewish rights self-hating Germans.
We realize that by criticizing Jewish fundamentalism we are criticizing a part of the past that we love. We wish that members of every human grouping would criticize their own past, even before criticizing others.
Modern racism (of which antisemitism is part) although caused by specific social conditions, becomes, when it gains strength, a force that in my opinion can only be described as demonic.
I strongly believe that antisemitism and Jewish chauvinism can only be fought simultaneously.
