We owe to Marx not only the Class War doctrine, but also a declaration of war to the propertied class: "The Communists everywhere support every revolutionary movement against the existing social and political order of things. In all these movements they bring to the front, as the leading question in each, the property question, no matter what its degree of development at the time. Finally they labour everywhere for the union and agreement of the democratic parties of all countries. The Communists disdain to conceal their views and aims. They openly declare that their ends can be attained only by the forcible overthrow of all existing social conditions. Let the ruling classes tremble at a Communistic revolution. The proletarians have nothing to lose but their chains. They have a world to win. Working men of all countries, unite!"[236] Marx's disciples have issued similar declarations. For instance, in the official programme of the Social Democratic Federation we read: "The Social Democratic Federation is a militant Socialist organisation whose members, men and women, belong almost entirely to the working class. Its object is the realisation of Socialism, the emancipation of the working class from its present subjection to the capitalist class. To this end the Social Democratic Federation proclaims and preaches the Class War."[237] "There is no way in which the Class War can be avoided. You cannot have the reward of your labour and the idler have it too. There is just so much wealth produced every day. It may be more, it may be less; but there is always just so much, and the more the capitalist gets the less you will get, and _vice versa_. We preach the gospel of hatred, because in the circumstances it seems the only righteous thing we can preach. The talk about the 'Gospel of Love' is simply solemn rubbish. It is right to hate stealing, right to hate lying, it is right to hate meanness and uncleanness, right to hate hypocrisy, greed, and tyranny. Those who talk of the Gospel of Love with landlordism and capitalism for its objects want us to make our peace with iniquity."[238] "The Class War is inevitable under the present form of property-holding, and for it there can be neither truce, quarter, nor ending, save by the extinction of the class system itself. The identity of interests between capitalism and labour is a shibboleth that can only be given any sane meaning at all in the cynical sense that the interests of the wolf and the lamb are also 'identical' when the wolf has got the lamb inside him."[239]
