Just got asked to fill in a diversity survey.
I answered 'prefer not to say' to every question, because I knew it was a waste of time when it asked me my gender.
I gave them the benefit of the doubt and thought maybe they are just using gender instead of sex, but no, my options were male, female, non binary and prefer not to say.
So I made use of the text box for prefer not to say and pointed out that gender is not a protected characteristic under the Equality Act.
For the trans question I said that my sex was observed and recorded at birth.
I normally wouldn't stick my head above the parapet, but this wound me up so much.
