While the nazis controlled germany, students took a subject known as race-ology. what did the students learn about? what did the teacher use for an example?

In the German raceogy class for the study of race they were taught that straight white Christian Aryan race was Superior to every Creed ethnicity race ever to exist in that they were to create living space or exterminate all they felt were inferior one of the teachers examples were comparing a black athlete to a white athlete back then most black athletes were viewed as Superior to whites because usually they were taller stronger faster because they had more muscle is something a teacher would say in a raceology class all except for swimming in which heavy muscles weigh you down and that's why you get The stereotype black people can't swim or app or at swimming hope this helps
