"Genocide begins, however improbably, in the conviction that classes of biological distinction indisputably sanction social and political discrimination"

In this quote, feminist author Andrea Dworkin is highlighting the dangerous belief that particular biological distinctions in between groups of people can justify discrimination and even genocide. She argues that this conviction, although apparently not likely, is the starting point for acts of genocide. Dworkin is mentioning the flawed logic behind using biological differences, such as race or gender, to justify unequal treatment and violence towards specific groups. By emphasizing the connection between social and political discrimination and the belief in biological differences, Dworkin is shedding light on the perilous nature of bias and the terrible consequences it can have. This quote serves as an effective pointer to challenge and turn down any ideologies that look for to validate discrimination based on biological differences.
