Reality, you are one of two biological sexes, male or female (or which ever chromosome mutation fits appropriately. )
I'm a transgender myself and I do agree with you. If you take my blood and check it, you'll see that I was born a male. Biologically I'm and will always be a male. We can't deny biology in that point. If I go to a Hospital and a medic asks my gender, I'll have to say that I'm chemically male but identify as a woman, simple.
I think that the matter is not to a biology extent, but socially. Idk about u, but I don't get sexually attracted to chromosomes ("Ohh... Those XY, gosh.") or see big tattoos in people's face "XY","XX" and treat them accordingly.
It's something like this: Your sex is male or female, simple. Born with that, dies with that. But socially if you choose whichever gender, it's ur choice. Transgender is basically this IMO.
