Yeah it's something i've thought more about too lately. People seem to get very irate at being asked to look at how they address people but i don't think it's a lot to take on board really. I'm cis-gendered and all of my main circle of friends are family are so i haven't really thought much in the past about how it makes people feel to be constantly misgendered. A lot of the assumptions built into how we use language can force people to have to constantly explain themselves and "come out" so to speak. It surprises me how many gay friends say they are still asked about boyfriends/girlfriends/husbands/wives by doctors or other public professionals in a way where it's automatically assumed they're heterosexual. Thought modern society might be at a point where we don't assume such things about people but it would seem lots of people are still being forced to come out/correct people a lot of the time. Trans issues are still a long way behind gay ones though when it comes to public understanding, so people should be given time to get used to changing attitudes rather than feel like they're being forced. Otherwise people who might have been open minded receptive will just push back and it'll be trans people who ultimately end up marginalised in the process.
