Some appear to have difficulty in defining a woman, why— It is very simple.
A WOMAN: a member of the Homo sapiens species having two XX chromosomes, which allows development of a body capable of reproduction of the species.
A MAN: a member of the Homo sapiens species having one X and one Y chromosome, which allows development of a body larger than a female with more muscle and bone structure and the ability for internal fertilize a female egg allowing her to reproduce the species.
A HUMAN: a creature defined into two sexes either having two XX or one X and one Y chromosomes. Each sex will develop specific hormones that permit developmental shape and organs for procreation.
The one having two XX chromosomes produce specific hormones to develop a procreative body for reproductive development and mammary glands that secrete nourishment for the reproduced offspring.
The other one having one X and one Y chromosomes produce specific hormones to develop large heavier bone and muscular structure for protection and food provisions of their family.
The chromosome structure is permanent, alteration of body appearances and its usage may allow pseudo role reversal and role playing, but not reproduction.
