This matters to me for ethical and religious reasons. Being a woman is a physical reality and that reality has led to women being discriminated against for centuries. Self ID worries me immensely because it feeds in the idea that the physical reality of sex no longer matters and could lead to exclusion of women from work and sports especially in minority communities. In a word it is not progress.
I have discussed this issue with friends and colleagues and spoken to my line manager in confidence.
I haven’t had any consequences, but there might be if I decided to go more public on the issue.
