Defining gender by chromosomes is outdated. Taking external appearance as a deciding factor is also outdated.
Ideally, everyone is just human. Everyone is „factual,“ so to speak. Genderless in the middle. „Being human“ means carrying an equal amount of yin and yang, of female and male energy, of soul and material information in one’s consciousness.
He who has more soul, yin, feminine energy available in his existence is then probably feminine. He rests, is accepting, passive and clear.
The one who has more material, yang, masculine energy is then masculine. He plans, acts, fights and judges.
In the relationship between the people nothing changed with this definition. The one resting in the middle would have enough as always in itself and would be whole. No matter whether formerly defined by his chromosomes as male or female. More Yin would attract as always more Yang. And more Yang more Yin. People would find each other as always and become a whole together. Independently of their genes.
It would only come to certain surprises with some. For example, with the woman who preaches hatred of men and separates and judges. She would have to find out astonished and irritated that actually she is the man. That she is the man who unites the preponderance of male energy in herself. She would have to realize that chromosomes alone are not decisive.
