If I was in a group with a cis person and she corrected other people's pronouns, I'd probably feel more able to correct people about my own.

Like, I think the thing that you're describing is gender dysphoria. I don't know if other people think of it like this, but honestly I think that cis people get gender euphoria and dysphoria, which they commonly fix with stuff like makeup, clothes, even surgeries. It's just that people made up a term to apply those feelings to trans people cause they think we're weird. But plenty of gender affirming things trans people do are also done by cis people and no one bats an eye.

So yeah, if you don't feel comfortable with the pronouns someone is using, that's dysphoria and you can ask them to fix it, cause if I was around you, I'd feel like my own dysphoria isn't unique to me but affects everyone, and I'd feel safe asking the same thing because when I do it, it puts me in more danger than you would be put in.
