"To be clear: there is no question that postmodernism has advanced the struggle against all forms of oppression, including the oppression experienced by trans people, those with disabilities or who face age discrimination, and many other forms of oppression that were neglected before postmodernist theories began to flourish in the 1980s and 1990s. ... At the same time, however, postmodernism also arose as a blanket rejection of political generalization, and categories of s and material realities, referred to as "truths," "totalities," and "universalities"--in the name of espousing "anti-essentialism." (To be sure, such a blanket rejection of political generalization is itself a political generalization--which is an inherent contradiction of postmodernist thought!)"
