No way to say this politely... poppycock! If one believes that the sexual orientation of a person is a function of the genetic makeup (what the Doctors involved with sexual change surgeries are writing about) you are just (again) factually wrong. Both the AMA and BMA assign "sex" in line with factors other than genetics.
Use the words the way you want. Just realize how wrong your beliefs are.
Panta Rhei! (Everything Flows!)
The reason a child is born naturally either male or female is because its either male or female its that simple. Its is either the female energy or the male energy. The dot on the yin and yang will always convert to what side it really is , if its male to female it will convert to female energy. This is a life fact that cannot be changed.
