As soon as you told me that I went and asked other trans people what the proper way to refer to xx and xy people if not biological female and biological male, and they ALL emphatically agreed that it is absolutely, undeniably, the proper way to refer to them, and is in no way offensive. They even asked me where I thought babies come from if there are no females/males. Then, I sent you the link to the conversation. Guess what your response was: "TERF!!!!!"
I have, and had absolutely no intention to insult anybody or call anyone by improper names or insults(you are still the only person involved that is doing this). I was simply trying to learn what the proper terminology was.
