It used to be so simple, didn't it? The midwife looked at the newborn child and announced, "It's a boy." if she saw a penis and two testicles, or "It's a girl" if she saw labia and vulva.
She then checked for hair-lip, cleft palate, and ensured that the anus was present and correct and that the bairn didn't have webbed feet, extra fingers and toes, or less than the normal five on each hand and foot.
Then she handed the baby to mother for inspection and got on with the rest of her routine.
Few midwives ever saw a true hermaphrodite, thankfully.
Children grew up with a name and pronoun deemed suitable to the sex their genital organs proclaimed they belonged to.
Believe it or not, most of us were perfectly content with the label we had been given, although perhaps not so comfortable with the list of things little boys or little girls didn't do.
Relatively few adults acknowedged sexual interest in a person of their own sex, openly at least or in individuals of either sex, and even fewer wanted to change sex, cross-dress etc.
Now we have men and women with the primary and secondary reproductive organs traditionally seen as indications of their sex, identifying with the opposite sex and claiming not only the right to dress and behave as women, although biologically speaking they are males, or as men, although biologically speaking they are females, but demanding the right to serve prison sentences in prisons for the sex they emotionally, but not physically, identify with, take part in sporting events for the sex they have assumed etc. etc.
Some but not all of these trans-gender persons, if I have understood them correctly, are not waiting for a sex change operation, nor are they content only to cross dress.
This leads to the situation where a human being who looks like a man insists on using female changing rooms and lavatories ,or one who looks like a woman using male facilities, and apparently we who are happy in our bodies have lost the right to complain about a "woman" complete with penis and testicles, beard and moustache sharing the swimming-bath's changing room with us.
Formerly this was, in Europe, the sole prerogative of males under the age of seven as far as women's changing rooms went, and did not exist at all in my childhood for little girls, as accompanying Daddy to the toilet or shower was unthinkable. So much so, that a female shop assistant was pressed into service if a small daughter shopping with her Daddy needed to visit the "Ladies' room".
Could we not just go back to referring to anyone with the physical attributes of the female sex as she, her and a woman, or girl, and those with the physical attributes of the male sex as he, him, and a man, or a boy?
And then accept the right of an individual to call himself she and dress as a woman, or of an individual to call herself he and dress as a male?
But let us be clear, those who assume an identity, but do not have a surgical change of sex are no more a man, than the soprano singing Cherubino is. Nor is the male cross-dresser any more a female than Cinderella's sisters are in the pantomime.
We have fortunately accepted that people can fall in love with a person of their own sex, so the fact that some feel like a woman but are biologically a man, or the other way about, should not be so hard to swallow.
But is it so unreasonable for a majority to demand that the minority also shows the rest of society some consideration?
