What is a Woman?

I consider a woman to be an adult human with mostly female attributes, they have female hormones flowing through their blood, two ovaries, a Uterous, lower average muscle mass than men, smaller skeletal frames and the 23rd Chromosome pair in each of their cells are both shaped like an X. This is not always true though, sometimes an affliction can cause a woman to lose some of their attributes, like a disease could cause their ovaries to be removed, but they're still a woman when that happens. 

Sometimes men turn themselves into women with hormones and surgery but mostly women are Humans with female traits from birth.  

Some people don't want want to belong in a gender they give themselves a pronoun that is genderless. The trouble I have is their pronoun could cause bad grammar if you write it down. 'They' is used instead of 'He'. For example, 'They gave up their seat on the bus for an old person, he said thank you to the person'. Or  'I fired they from their Job'; 

Teaching madness

One thing I worry about is what my son will be taught when he goes to school. I was taught sex education when I went to school so you would have Mr Shakespeare saying it is ok to shake your spear. You would have Mr Williams saying what a willy is, then you would have Mr Dickens explaining where the Dick goes in. At least they teach me enough to know if I was being molested by an adult, that is fair enough. But now it is different because you also have Mr Confucius teaching them that there is a gender spectrum. ????

The way I understand it is if you have a y chromosome, you are a boy. If both your chromosomes are x then you are a girl. One or the other. No need for complications. Wouldn't it be better if they just taught grammar and logic with maths. Let kids learn to love reading and learning and not be filled by with all this confusion.
