I wish they would just engage their brains.
"A significant part of the female reproductive population use hormonal medications/ devices that prevent menstruation and are therefore not people who menstruate"
And the fact that they require hormonal medication to prevent menstruation means that they are at a disadvantage compared to men. Many women lack access to any kind of medical care.
"A small part of the female reproductive population is pregnant or breastfeeding and so, are not menstruating"
Which also impacts on their rights.
"A small part of the female reproductive population cannot menstruate"
"A small part of the female reproductive population has experienced early menopause and so, are not menstruating"
And in both of these instances it is likely that the reason for not menstruating will have a long term health impact and they will require medical care.
The handy word that defines the group of people affected by menstruation is 'women'. If an adult woman doesn't menstruate, there will be a medical cause, whether that his menopause, hysterectomy or something else. Men just don't menstruate.
"A small part of this population do not identify as ‘women’ or ‘girls’"
I would imagine that a very large part of the population don't 'identify' with any gender stereotype, yet the consequences of sex cannot be avoided. Wouldn't it be better if we just agreed that 'woman' is a neutral word that does not dictate your identity?
"Black Trans people are disproportionately victims of violence, simply for existing. They are made to feel invalidated and mocked for menstruating. Nobody should be made to feel shame for their body."
There is nothing shameful about being a woman, and JK Rowling has not mocked anyone. 'Validity' is no more linked to your sex than it is linked to your blood type.
However, as with 'woman', if 'trans' no longer has any objective meaning, it is impossible to carry out any statistical analysis on whether either group is more likely to be a victim of violence. Without recognition of sex, the concept of 'trans' does not exist.
"We implore you to spend some time researching"
Likewise.
