Adolf Hitler in Mein Kampf:
That is the point when I saw two dangers approaching. Previously, I did not truly understand their names or their importance to the German people’s existence. Their names were Marxism and Jewry.
For even today these heads have not understood the difference between Socialism and Marxism. Especially when, in addition, they discovered that in our meetings we principally did not address ladies and gentlemen' but only 'fellow citizens,' and that among ourselves we spoke only of party members, the Marxist ghost seemed to be proved for many of our enemies. How often we shouted with laughter at these stupid bourgeois cowards, in the face of the intelligent guessing at our origin, our intentions and our goal!
But even more: the Jew becomes suddenly also 'liberal' and he begins to rave of the necessary 'progress' of mankind.
Thus he gradually makes himself the spokesman of a new time.
Of course, he destroys then also more and more thoroughly the foundations of a truly useful national economy.
We chose the red color of our posters after exacting and thorough reflection, in order to provoke the leftists by this,to bring them to indignation and to induce them to come to our meetings, if only to break them up, so that in this way we were at least enabled to speak to these people.
