As anarchist communists, we are against reformism. However, we are for reforms. We believe that fundamentally the entire system of capitalism, the state and all systems of hierarchy, domination, oppression and exploitation of humans over humans must be abolished and replaced with a direct democracy, egalitarian social relations and a classless economy that bases contribution according to ability and distribution according to need. However, such a social revolution can only occur through the power of the popular classes themselves from the bottom-up. In advancing towards such a social revolution and a free and equal society, we must build our power in preparation for this fundamental transformation of the world, building on struggles along the way. Ultimately our demands will be too threatening to the elite classes for them to bear; and their resistance to our drive for freedom will be too much for us to tolerate any longer.
Why should we, the proletarians, have children if they are taken by the capitalists to be killed metaphorically in work and by the militarists to be killed in reality as soldiers?
