We got a message round to take part in this - it's the usual guff - but I put under gender "my sex is female, gender is a socially imposed construct" and also told them that women can't "be themselves" in academia. Will they care do you think?

However you need your institution code and name so you'll probably have to search on your University web pages for that. On ours it was under "equality and diversity" but maybe try HR as well, or News.
As I said on the general chat thread, I don't know any out lesbians or bi women who are academics at my institution though there are a small number of out gay men. But some of this may be subject specific as it's not a theoretical debate in my branch of STEM (or at least nobody in my department specialises in it - it is I know possible to research this area in my discipline).
