...for biologically female people, i.e. people who are of the sex class which produces large gametes, generally have xx chromosomes, and have common biological traits of having a vulva/ vagina and associated other biological characteristics.
There has to be language which easily allows for people with these characteristics to be grouped together. Obviously this word has (and still is) women /girls, but in expanding the meaning of these words to include people without these characteristics the words become meaningless as the biological category.
Do people who want to expand the meaning of the word woman think it is entirely unimportant that there be a word which easily allows people who have these characteristics to be easily classed as a group?
