Sure. And maybe you don't find it offensive.
But you're suggesting that those who do are "wrong" or only feel that way because they must be Transphobic.
Rather than that they legitimately feel offended by the language. This is reductive and diminishing.
I was pregnant well before this issue was ever a thing. I loved being pregnant, biologically. It was a trip.
I did NOT enjoy the societal perception of pregnant women's bodies being up for public consumption and fetishizing.
Based on that, if someone had referred to me as a birthing person when I was pregnant they would have been lucky to not find themselves with a bloody nose cause I likely would have decked them.
You made a choice to center the opinions of people who will never be pregnant and therefore cannot ever understand the experience. I don't know why you would make that choice, it's yours to make. I'm just curious as to why you would place an opinion from someone who will never have that lives experience over your own lives experience and thus, choose to throw all your fellow sisters under the bus as well.
