Historian Ian Kershaw:
"Hitler's well-known reply to [fellow soldier Adolf] 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 unshakeably be the removal of the Jews altogether.'"
