"Gender identity = what sex you think you are."
na, zip to do with sex ------------- this is actually easy stuff and just gets confused by trolling idiots - mostly usually uneducated ---
this is a simple version - but, accurate
"Gender refers to the characteristics of women, men, girls and boys that are socially constructed. This includes norms, behaviours and roles associated with being a woman, man, girl or boy, as well as relationships with each other. As a social construct, gender varies from society to society and can change over time."
Identity is merely how one identifies oneself
then
one can list - society by society - the characteristics of man or woman
if someone has a mix of man characteristics and woman characteristics - and they don't feel like either - then, they self identify as whatever they feel like
personally, I don't see any management problems from there in -
we can all use the same dunnies or change rooms or showers -- just like we do in planes or ships or in houses
it's a big socially constructed load of horseshit -------- one is what one feels one is
