At I school where I worked, a female teacher overheard a teenage boy using the word 'gash'. She confronted him and insisted the correct word was 'vagina'. The boy said, 'no miss that is the vulva'. The boy was right. I've seen her using gender criticism on FB.
There are gender critical women out there who insist on correct biological terms, but don't seem to know the difference between a vulva and vagina. A surprising number of women think they pee from their vagina.
My mum once heard a woman complain that she doesn't want trans women in public toilets because they don't have a cervix.
My mum told her, 'keep the door shut and locked, and if anyone can see your cervix, go and see your GP'.
