You shouldn't have to out yourself by showing your ID card that lists your sex which could accompany a chance of discrimination, violence, and so on.
^ I SOOO agree with that! I went to get my ears pierced 2 months ago, after waiting for like a quarter of a year for them to get those particular ear rings in, I left my ID at home because it would out me and didn't think I needed it anyway. I shaved myself real good, put on a dress and some lip stick and brought my purse with me, I even used my female voice too. When I got there, had to wait around, risked making it to an appointment (It all worked out with said appointment but I was pushing it/myself) and finally, before anything else could be done, I was asked to sign a waver form if something went wrong they aren't responsible, (Ok I'l just sign with my gender neutral name I said) but then she asked to see my ID and I told her, I didn't have it with me, she then said to me "If you don't have it, I can't pierce your ears" and I left without them pierced, and upset/mad at the world and even woman born with a female body. So, do you think I ever got them pierced? NOPE! Why? Because of the ID outing me and how this world is filled with such dang discrimination!
