Antisemitism based on purely emotional grounds will always find its ultimate expression in the form of pogroms. A rational antisemitism, however, must lead to the systematic legal fight against and the elimination of the prerogatives of the Jew. ... Its ultimate goal, however, must unalterably be the elimination (Entfernung) of the Jews altogether.

Hitler’s well-known reply to Gemlich, dated 16 September 1919, is his first recorded written statement about the ‘Jewish Question’. He wrote that antisemitism should be based not on emotion, but on ‘facts’, the first of which was that Jewry was a race, not a religion. Emotive antisemitism would produce pogroms, he continued; antisemitism based on ‘reason’ must, on the other hand, lead to the systematic removal of the rights of Jews. ‘Its final aim,’ he concluded, ‘must unshakably be the removal of the Jews altogether.” | Ian Kershaw, Hitler: 1889-1936 Hubris, pp.125-126
