[6] On 27 March 2006 speaking on Radio Maryja, he made antisemitic remarks when he said that "Jews are trying to force a ransom from our government which they covertly call restitution".

Michalkiewicz also said the country was being "humiliated" by Jews "at the site of the former death camp Auschwitz" and in April, 2006, was reported in Gazeta Wyborcza as stating that "men from Judea ... are trying to surprise us from behind", and referring to the World Jewish Congress as "a main firm in the Holocaust Industry".

[9][10][11] In 2011, Michalkiewicz, known for supporting the Catholic Radio Maryja, condemned the MP Jan Filip Libicki for his "ultra-Catholicism" on the pages of the radical right-wing website "Nowy Ekran", followed by offensive statements about the religion.

The anti-Catholic message was distinguished by the editors of "Idź pod prąd" (Go against the current) - a journal combining ultra-right views with aversion to Catholicism.

[12][13][14][15] Michalkiewicz publicly promotes antisemitic conspiracy myths, including presenting Jews as enemies of Poland who seek to seize power ('Jewish occupation'), accusing them of reaping financial and political benefits from the Holocaust (the author even undermines this concept), as well as the desire to destroy the foundations of Latin civilization.
