What was created by teaching children Aryan and non-Aryan categories in the Nazi worldview?

Correct answer: Normalisation of racial thinking from childhood

The direct answer is A: normalisation of racial thinking from childhood. In the Nazi worldview, children were taught that people belonged to supposedly superior Aryan or inferior non-Aryan groups. This was not valid science; it was racist propaganda. Step by step, schooling repeated these labels, repetition made prejudice seem ordinary, and ordinary prejudice influenced how children judged neighbours and classmates. Option A is correct because it describes the social result of such teaching. Option B is wrong because democratic tolerance respects equal rights and different people, whereas Nazi education encouraged exclusion. Option C is wrong because scientific objectivity depends on evidence and fairness, not invented racial hierarchies. Option D is wrong because religious harmony means peaceful respect among faiths, while these lessons promoted division and persecution. Remember: Nazi racial lessons aimed to make discrimination seem natural.
