Despite his beautiful childhood, Fredy experienced open anti-Semitism as a schoolboy. When he and his classmates participated in the midday church bell ringing in the Catholic church, he was thrown out of the church by the sexton with the words, "You have no business being here. You get out of here, you killed the Saviour."

As a child, after a cattle market in Nagold, he had to experience how a non-Jewish cattle dealer said about his father: "Too bad they didn't gas him too, then I would have the best business now."

Fredy also developed a keen sense for subliminal anti-Semitism and open and covert hostility toward Israel in society.
