I hear you. Things are too labeled in society. Like deodorant and shampoo is the same for everyone...why do we need to add "for men" or " for women" anyway? I am a cis woman who has no issue buying "men's" razors/shampoo/deodorant simply because its cheaper and since i use unscented products it doesn’t matter to me. I also buy and wear boxers cus they are more comfortable. I dont consider myself non-binary or trans or a cross dresser because Im secure in my womanhood and don't consider it a big deal.
As far as the phrase " Pregnant People" it does sound weird when you say it aloud. Its too illliteritive. Why not just Pregnant if theres a need to generalize or pregnant individuals?
I feel that its just as easy to actually ASK the person in front of you what term they prefer you use and then just use that term rather than try and generalize and lump everyone together. As a cis women i wouldn't care to be referred to as a pregnant person but it would've really bother me enough for me to correct them. If they called me a pregnant man, I wouldn't get all offended and think they hate all cis women, id just laugh and correct them. Its really not hard to just communicate with the person in front of you. Its far easier than trying to change all language to be inclusive.
