"Trans feminists seek to interrogate society’s ingrained assumptions about the social and cultural meanings we ascribe to biology. They also generally incorporate an analysis of intersex people, who do not fit this reductive model, and who have suffered historical and ongoing mistreatment at the hands of a medical establishment obsessed with imposing binary biological sex on to bodies that don’t ‘fit’. The experiences of trans and intersex people show us that not all humans fit perfectly into two clear-cut categories of biological sex; indeed, the belief there are two separate sex categories is itself an erasure of sex variations that occur either naturally or through medical modification. The global dominance of men over women can never be dismantled while simultaneously maintaining, preserving and reinforcing the binary model of sex and gender."
