The feared sharpness of Dr. Goebbels’s language was a result of his honesty. At a time when the word “lie,“Or even the direct term “liar” were thought unrefined and unusable in the columns of the German press, although they carried lies in their columns, Dr. Goebbels did not hesitate to call one who lied a liar. When it is necessary to call things by their proper name, when it is necessary to expose persons, then things are called by their name and people are presented in such a way that even a dog will no longer take a bone from them. The journalist and speaker Dr. Goebbels did not change his impolite methods, even when he faced a certain ban or a certain legal process.
