A second aspect of feminist critique centers upon the notion that even where women have become criminologists, they have adopted 'malestream' modes of research and understanding, that is they have joined and been assimilated into the modes of working of the masculine paradigm, rendering it simultaneously gender blind and biased (Menzies & Chunn 1991). However, as Menzies and Chunn argue, it is not adequate merely to 'insert' women into 'malestream' criminology, it is necessary to develop a criminology from the standpoint of women. At first glance this may appear to be gender biased against the needs and views of men. However, this claim is based on a position developed by Nancy Hartsock known as standpoint feminism. Based on the work of Marx, Hartsock suggests that the view of the world from womanhood is a 'truer' vision than that from the viewpoint of man. According to Marx (Marx 1964, Lucacs 1971) privilege blinds people to the realities of the world meaning that the powerless have a clearer view of the world – the poor see the wealth of the rich and their own poverty, whilst the rich are inured, shielded from, or in denial about the sufferings of the poor. Hartsock (1983 & 1999) argues that women are in precisely the same position as Marx's poor. From their position of powerlessness they are more capable of revealing the truth about the world than any 'malestream' paradigm ever can. Thus there are two key strands in feminist criminological thought; that criminology can be made gender aware and thus gender neutral; or that that criminology must be gender positive and adopt standpoint feminism.
