The silencing of trans people, and trans women in particular, in feminist spaces isn't just limited to discussions about pop culture, unfortunately. Cis voices are centered over trans voices consistently, and sometimes very dangerously, while trans folks are denied autonomy, identity, and even our own experiences.
Trans people are excluded from women's shelters. We are denied medical care. We are told that our opinions have no worth and value and are treated as 'fakers.' It's not just the mainstream media that misgenders trans people; I see it happening in feminist spaces all the time, along with prurient speculation about whether or not trans folks have had reconstruction surgery or what their 'real names' are.
