Piasecki continued publishing anti-Jewish texts also following the German occupation, in June 1940 he published article in the Polish National Democracyunderground newspaperWalka titled "Gubernia Generalna — Paradisus Judaeorum" in which he stated that: Because Piasecki himself was of Jewish background, his critics pointed out that the measures he supported against Jews, would mean he himself would be forced to edit only Jewish magazine in Yiddish, or even be forced to leave Poland if they would be enacted The German atrocities following 1939 invasion of Poland made Piasecki reject his previous antisemtic views
