A new textbook for secondary schools, developed under the auspices of Poland's conservative government, has been criticized by some members of the public as an attempt to indoctrinate young people.

Criticism of the modern history textbook, entitled "History and Present", these days focused on the passage describing modern approaches to sexuality and childbearing. The text seems to express a negative attitude towards in vitro fertilization without explicitly mentioning the term.

The excerpt reads: "Increasingly sophisticated methods of separating sex from love and fertility lead to viewing sex as entertainment and fertility as human production, one might say procreation. This raises the fundamental question: who will love the children, created in this way?

The leader of the opposition centrist party Civic Platform, Donald Tusk, during a recent meeting with his supporters, he criticized the extract, but there were also criticisms of the Minister of Education Przemyślów Charnek and other members of the Government.

"You can read that children conceived through in vitro fertilization are children from breeding farms that no one wants," Tusk said.

Addressing government officials, he said, “There is no limit to their meanness. There is no line they haven't crossed."

The Polish Ministry of Education denies that the passage refers to the in vitro method.

Czarnek threatened to sue Tusk for defamation if the former Polish prime minister and former president of the European Council did not apologize.

"Neither I nor the ministry write or publish textbooks," he stressed.

In his words, "History and the Present" does not say that no one wants children conceived through in vitro procedures.

The Ministry of Education responded to Tusk's remarks by tweeting that only a "sick and hateful" mind would interpret that part of the textbook in this way.
