[4][5] In August 2022, the Polish Ministry of Education and Science authorised Roszkowski's 1945–1979: History and the Present textbook for use by liceum and technikum schools when teaching a newly introduced subject of the same name [pl]; scholars and commentators criticised the book as essentially being a far-right tract that, in addition to other claims, stigmatised IVF-conceived children, equated feminism, liberalism, and other popular ideologies with Nazism, depicted neo-Marxist influence as being a reason for the prominence of women's rights and gay rights movements, and was critical of the Black Lives Matter movement and of negative assessments of the Crusades.

[9] The issue was compounded by an alternative textbook being slow to receive official authorisation[6][8] and by Roszkowski's book being available for sale in state-run post offices which, under the Law and Justice government, have often been criticised for selling publications that are seen to be aligned with that party's beliefs.

[10] Roszkowski branded criticism of his book as being "a certain offensive, manipulation of public opinion, a kind of preventive censorship" and said that the passage purportedly referring to IVF did not in fact address this subject.

[13][14] In the meantime, Roszkowski had written a follow-up textbook covering the period between 1980 and 2015, with this newer book also receiving approval from the Ministry of Education and Science.

[15][9] Just like the first book, there was considerable controversy over the new book's content and sociopolitical slant, including its comparison of what it called "LGBT ideology" to the ideology of Marx and Engels, its claim that criticism of John Paul II mainly took the form of aggressive attacks by left-wingers, and its sympathy to global warming denial and to conspiracy theories about the 2010 Smolensk crash being a deliberate assassination.
