@Oneironott I think part of it is that gender and dysphoria is mired in epistemology. So having language makes it easier to process and explain feelings. Sometimes, I wonder if you could describe gender as the language you use to explain your relationship to your body's assigned sex, your presentation, and sense of self. Rather than some kind of psychological construct that exists deep within us.
Trans people have complicated relationships with those things, so our language gets complicated. Cis people find it confusing because they don't need much language to explain their gender. I admit this is half baked.
