"Epistemicide" is a term you should become very familiar with in all discussions regarding trans oppression. It sounds fancier than it is. The term is related to the concept of epistemic injustice. In essence, trans people have historically been subject to a form of epistemicide: our stories, histories, testimonials, ways of life, all erased and buried to maintain the patriarchal myth of dichotomous, naturalized, immutable sex. We are then further marginalized through epistemic injustice, prevented from participating in the processes of knowledge-production, our testimonies devalued, our voices suppressed and our identities defined for us, not by us. The perception of us shaped by others, instead of ourselves. The conversation about us dominated by the voices of those who'd rather stamp us out, shouting over us constantly. If you're not accounting for this as a central mechanism animating transphobia, you're missing a lot of the picture.
Theory bite!
This is probably something that cis people would find useful, as much or more than trans people, because a lot of cis people participate in it in conversations about transness and trans folks ;3
