which you know is just nitpicking. The reason it has been relabelled from women to female is precisely because of the need to protect women's sport for biological females.
There is a choice. Either transwomen are not women and race in the trans and binary category or transwomen are women, but cannot race in the biological female category.
The compromise solution is to have a male and female category and an open category for anyone not biologically male or female or who is uncomfortable racing under those designations.
Your friend has a choice, and is not being prevented from participating or competing. If she chooses not to because of idealism, that's down to her. It's insane to try and make rules to cover every possible designation.
Not nickpicking. I don't think you are seeing a problem that is in plain sight. The CTT say the changes are being made to make sure that there is no biological advantage of trans people over others.
My friend is biologically female. My friend has no biological advantage over other females. The two new categories are 'female' and 'open'.
My friend is like Aurora in as much as they have opinions about gender identity, or more specifically how people are treated according to the expectations of others. My friend does not want to hear expressions such as 'not very ladylike', 'she's a bit butch'. and other expressions the hear, such as like 'looks like a man'. In one previous job my friend was told by her male boss without any context, 'I might as well shag a man as you'.
My friend used to be a teacher, but now works for the NHS. My friend is six feet and a half inch tall and prefers to wear their hair short. My friend has a voice at the lower end of the female range. At work, they work in a unform, too often people misgender my friend due to their perceptions of what a 'woman' should look like. In public toilets my friend has been very rudely challenged by women who make assumptions. My friend has been told too often that they are 'too tall to be a woman'.
Now, under the new rules, my biologically female friend is being told by the CTT that they can not compete in the female class, but must instead compete in the open class where Aurora and yourself have been saying that they will have a disadvantage.
My friend is less troubled by concern about competition, but my friend is furious that the CTT think that they are in a position to regulate who can compete not just in a biological class, but also what words a competitor uses about their gender identity. This ruling does just not reflect decisions made by considering the science of biological sex, it also reflects their bigotry, in my friend's opinion.
