Thoughts on writing a character as cis when most of the fandom sees them as trans?

To preface, I am trans. And I have a lot of below the belt dysphoria. Fic is one of the places where I don't have to worry about such things. Obviously I realize writing a character as trans can be cathartic and a way to see ourselves represented in media where we otherwise wouldn't be. And sometimes that's the case for me too. But because of my dysphoria, my experience doesn't usually line up with that.

I started writing in a new fandom, and noticed that one of the characters is widely seen as trans and plenty of tweets/tumblr posts complaining about those who write this character as cis. Some seem genuinely upset when this character is interpreted as cis and I don't want to hurt my community further.

So now I'm worried with my own fic. Worried I'll upset people, worried that this fic will be shunned, maybe a little worried that I won't even have an audience. I also have an anxiety disorder so it is totally possible I'm over thinking everything.

I could use some different opinions, as I know the replies here are usually more varied than on other social media platforms. Maybe I've just been stuck in an echo chamber?
