In the first case, a Protestant evangelical primary and pre-school in Borgerhout, a district of Antwerp, was revealed to be using a fundamentalist Bible basis to teach children to question evolution. "We say that there are many people who believe that is how the world came about," said Luc Borkes, director of the Zonnebloem School, which has 29 pre-schoolers and nine first-year pupils. "We're not saying that creationism is proven, but we raise questions about evolutionary theory. In religious lessons, we learn the Creation story. And in biology lessons, we say that the hand of God is involved in our existence."

Smet's problem is that the school is subsidised by the government and is required by law to adhere to guidelines regarding the content of lessons. However, evolution is only on the official syllabus of secondary schools, and religion education is not in the government's remit, making intervention impossible.

A similar problem arose when a number of Jewish schools in Antwerp were revealed to be censoring textbooks in order to, for example, black out the appearance of a women's bare arms, remove words like "pope" and "church" and, like the Protestant school, remove any mention of evolutionary theory. Matters like sexual education are passed over completely.

Michael Freilich, editor of the magazine Joods Actueel, defended the policy. "In our community there are no rapes, no teenage pregnancies and no sexually transmitted diseases," he told De Standaard. "Other people in Jewish schools say almost exactly the same is true. They all explain that it is due to the strong teaching about sex and the relations between men and women, or boys and girls."
