My daughters, you, me, anyone - shouldn't have to shower WITH anyone (unless that is by choice). There should be no such thing as open showers. That concept is one of the most insane things I can imagine. Why should little boys have to shower with grown men? The concept goes both ways here and people forget that.

First and foremost, the best way to address this whole bathroom "kerfuffle" is to look into what makes restrooms and locker rooms the following - Safe, Private and Accessible. Address those, without discrimination and both sides win. Bathrooms should be in well light, well trafficked areas. Locks should always work. There should be floor to ceiling dividers between stalls, if not full walls. Best are individual bathrooms with solid doors and locks. Private, well that gets covered by the dividers between stalls or individual unisex bathrooms. Accessible - meet or exceed all ADA standards. Make bathrooms work for parents with young children who need diaper changes. Think about adults who need to accompany other adults to the restroom, such as those with handicaps or elderly. (If my dad is out with my mom, and she is having physical difficulty of varying sorts, he should have an option for going into the restroom to help her.)

All of those address the safety issue of bathrooms without discriminating against any specific people. NC could have gone that route with regard to bathrooms, but they choose some very unenforceable standard of what's on a person's birth certificate. Well, that might lead to someone that looks outwardly like a man in the women's bathroom, but their birth certificate says female, so.... How can we enforce NC's law without violating the privacy of everyone using the restroom. Do I have to "prove" I'm female to go in? Drop my pants? Show ID? If a transgender person "passes" for female in looks, is that ok? What about a female, born female and identifies as such, but looks kinda manly? Who makes this call? What standard is used? How do you know that man with the beard in the restroom is or isn't a born female that has transitioned?

As for you wanting a legal definition of transgender - well the medical definition is relating to, or being a person who identifies with or expresses a gender identity that differs from the one which corresponds to the person's sex at birth. I can go even further with you into the science that is showing more and more about gender and gender identity than previously known. It's not just physical genitals. It's not just chromosomes. There are many, many other factors that come into play in determining our gender identity. Why is it that most women aren't big sports fans and men are, but then you have women like me that enjoys sports more than my husband? (And not because I was raised that way all that much. Outside of KY basketball, my family didn't watch sports much.)
