How people want to identify is not important to me and I can respect it. If you want me to use certain pronouns to describe you I take no issue. How I personally view your biological sex is another matter. There is a difference and to suggest otherwise can have deadly outcomes.
I'm a cardiac RN and males and female present differently when it comes to diagnosing a possible infarction. Though men and women hearts are structurally the same, women likely have less troponin proteins then men. Troponin I proteins are released into the blood stream when the heart is damaged and we use that to determine infarction vs ischemia. (There are other tools also such as ct scan and ekg for st elevation.) Biologicals males and females have different specific lab value we check to determine this. In addition to other tests, a course of action is determined by the medical doctor. I can tell you from experience that it is a difference if that patient will be on an heparin infusion over night or whether the Cath lab will do a heart catherization that night.
In addition to working as a cardiac nurse I also work per diem as an addiction nurse. The focus is for our clients to attend group therapy and proceed with their personal therapy session. The company have two separate dorms on a 25 acre land. Females are in one dorm and males in another. There are no private rooms, it is double occupancy. The company allows men that identify as women to dorm with the females. There have been countless incidence where the transgender females are having sex with the females. Not to mention other issues that arise when you place a biological male with females that have had sexual trauma. All the wikipedia post doesn't counter real world experience. Additionally, for anyone that has completed college will tell you that wikipedia is not an accepted form of reference and would get you a nice F on your paper.
