The truth is that someone is comfortable in a space feels comfortable if his/her gender identity matches the sex of all those in the space - and the greater the dissonance between the two, the less comfortable people are - but it is impossible to have that discussion because gender critical feminists refuse to accept that gender identity exists.
I would like to see an explanation that in some way objectively explains and substantiates the concept of 'gender identity', I can't find one anywhere.This means that I have very little recourse when I try to analyse it. It seems that either I can view it as a weak claim with little or no material substance, akin to a 'religious' experience or I can view it from a personal standpoint.
If I view it from a personal standpoint it makes no sense to me whatsoever. I was born female, I was socialised in a culture that has particular expectations of those who are born female. I do not however 'feel' female. I know I am female because that's how I am classified. I know what I have in common with other females which is a particular lived experience that I share both biologically, socially and culturally. How I 'feel' impacts on aspects of my material existence but it doesn't account for it.
It doesn't necessarily matter how I 'feel' in a space, I actually prefer male company on the whole. I've also spent more time with gay men, transwomen than I have with other women. I find a number of the topics that as a 'woman' the culture expects me to engage with rather irrelevant.
HOWEVER I do know that being female makes a difference to my material reality and that of other females. I don't feel more comfortable in certain 'female' spaces because I am sexed 'female' or culturally gendered as such but because in material/factual terms I am safer. Women in parts of India don't walk for miles to find a women's loo because of lack of dissonance between their sexed/gendered selves, but because it is materially safer.
This leads me to another problem I have, the issues that are attributed as 'petty' ideological concerns of UK women have extensive implications. If this idea that safe spaces for women depend on gendered identity becomes the dominant how will that impact on wider policies for women here and elsewhere?
