Kindred, Cochonette, cool
I am a pretty cis woman myself, although I don't believe in the gender binary and support those who want to identify outside of it.
Speaking of which, have you heard of this Swedish couple
who raised their kid without telling their sex to strangers? I find it pretty awesome that the child will be able to develop a gender identity without every random person's pressure (the parents do identify within the gender binary). And frankly, I think that for the most part, whether one has a vagina or not, or identifies as a woman or not, is no one's business. Why would you need this information to interact with a preschooler, or on an internet forum?
