The sex/gender distinction of the 20th century and now deeply popular among LGBT+ circles in the 21st century was one step forwards, two steps backwards. Although it provides a simple “explanation” of trans people, it ultimately cements sex and thus patriarchy as the natural state of things. Human sex has always been a social concept with biological justifications applied retroactively and selectively. The proletarianization of women and advances in medical science lay bare the absurdity of sex and for the first time in human history create the conditions for the world-historical abolition of sex and male supremacy. As the proletarian revolution self-abolishes the proletariat, so too does the transsexual-feminist social revolution self-abolish the woman and transsexual. Down with cisgenderism!
