Your experience with your trans friends is wholy different than mine. Maybe its regional or cultural but the FTM trans I know well wouldn’t object to being referred to or lumped in with pregnant women on a general basis and if they did they are fully capable of correcting those refering to them with whatever term suits them. For non-binary pregnant person may sufice, for some FTM they may prefer pregnant man. Thats kinda my main problem i think. Health care is such an individual thing. There’s absolutely no reason why a doctor, nurse, or receptionist cannot use whatever term the person in front of them prefers instead of the extremely illiteritive term pregnant people. Why not just say the Pregnant? Or heck pregnant individuals if addressing a group? Pregnant people just sounds strange on the tounge and doesn’t really suit everyone. As a cis female person I want to be referred to as a pregnant woman not a pregnant person. Your friend maybe would have preferred pregnant man? Idk but why can’t we just meet individuals as individuals that they are?
What ever happened to just talking to people? Why can’t we change our language to fit the circumstances at hand instead of trying to find one size all solutions? Even among FTM or Non-binary individuals there’s no agreement. Some are fine with pregnant woman, some what pregnant person/individual, some want to be referred to as a pregnant man! I dont need to agree with any of that to honor the person in front of me and use their preferred term. Just tell me! Don’t assume malice where mistake is probably more likely.
I’m teaching my child to give others grace. Correct others who may mess up his pronouns. If they refuse to try to change then you can be offended. However, understanding that most people are just creatures of habit and don’t understand how the other person feels goes a long way towards the end goal of mutual respect. Instantly chastising them and assuming ill intent does not. Speak up for yourself and try to be respectful until its clear the other person isnt willing to be respectful back.
