He also killed homosexuals and gypsies.
Years ago l watched a captured German film. This German officer was standing behind a long table that had things on it. He was in one of the constation camps. The back round looked like an empty field. Jumping to the part you are interested in. He started naming off the types of prisoner he had in this camp. He named groups l knew and some l never heard of then about the 10th or possibly 15th he said jews. I do not know if he was going from most to least or just randomly naming the groups of people. Only towards the end of the war did he do what we call the final solution, killing the Jews. Thats all.
