Maybe if you don’t want people to accidentally think you’re a man then maybe put a little bit more effort into not looking like one. You have a 5 o’clock shadow for Christ’s sake. There are plenty of trans people out there who don’t get misgendered because when you look at that person you know what they identify as. People like you are looking to blur the lines between genders so situations like this can occur, where you can bring attention to yourself while harming someone else. If you identify as transgender and someone mistakenly misgenders you, that’s not on them, that’s on you.
