Why was Adolf Hitler so racist to the Jewish people in his time?

It is
fallacious to assume that Hitler's anti-Semitism was unique or even new. Jews throughout Europe
had been vilified since the Middle Ages because they were (1) Not Christian, (2) persisted in
retaining their traditional religion, culture and values, and (3) were the money lenders at a
time when that practice was denied to Christians. Jews in England were slaughtered immediately
after the coronation of Richard Lion Heart. Similarly, before the First Crusade was launched,
Peter the Hermet's Peasant's Crusade killed thousands of Jews in continental Europe.

Although most Europeans by Hitler's time had learned to live peacefully with their
Jewish neighbors, an anti-Semitic element was always present. As a young man, Hitler was an avid
reader of an anti-Semitic (and at times pornographic) periodical known as Ostara.
He was also enthralled with the music of Richard Wagner, who was a virulent
anti-Semitic. Because many of the early Communists were Jews (Marx, Trotsky, Rosa Luxembourg)
Hitler easily associated Communism with Judaism. The threat of a communist revolution in Germany
following World War I lent itself to the connection in Hitler's mind.

Hitler's anti-Semitism was thus an element of his culture. This alone does not explain
his attempts to exterminate them, however. All National Socialists were anti-Semitic and
pro-Nordic; Hitler's gift forand his personal charisma brought him to the forefront of that
movement and he thus became the figurehead for the anti-Semitism that was already
present.
