I also want to thank you for starting this project! I have always felt like the trans* experience of abuse is very complicated, and it is so easy to feel out of place even in safe spaces like this where things still tend to be more tailored to cis experiences.
From a trans man's perspective, my answer is "sort of, I guess...?" Despite having always presented as masculine and using a male name, my abusers did the misgendering for me and never really gave me the chance to correct them or stand up for myself. (Although I didn't exactly have the confidence to be insistent about my own identity, being raised by a disapproving narcissist and generally conservative family.) I was basically silenced and objectified; it didn't matter that I was doing everything I could to present as masculine.
Sometimes, I wonder if I wasn't actually just a fetish for these people (hence blurring the gender line on purpose from their perspective) and too young/naive to put two and two together while enduring the abuse: granted, I was 19, but a naive 19 year old.
At first, I felt like I had to accept being misgendered when getting help, but I never had an experience where I thought coming out to a therapist would have caused a bad reaction - I often talked in very gender-neutral language when describing my trauma, and I think the professionals caught on (in addition to the obvious signs in my appearance) and were careful not to gender me at all until I directly said "I identify as male."
Where the misgendering was forced ended up being in situations trying to find support from friends or, well, my mother. I rarely spoke about my abuse, but if I ever did, I would have to bite my lip and accept the misgendering in order for the conversation not to immediately shift to there being something messed up about me instead of about my experience.
I hope there was something useful in that little rant, I hope the documentary is a success!
