I looked at the website of the museum a couple of years ago. It gave the impression that vaginas are weird floating things in the air, apparently randomly attaching themselves to some bodies and not to other bodies, and nobody knows the reason for that.
It was someone from that website who on Twitter proposed the term 'vulva people', to denote individuals of the female sex.
I got the impression that people working there had not thought this through on any deeper level, and wanted to be very virtuous and kind, even if the cost of that was to flush most vulva people down the toilet.
This is the impression I get from lots of young feminists who tend to believe that all necessary sex-based rights have already been won.
As an aside, isn't it interesting how two trends are perceptible at the same time and pushed by the same groups: One is to erase all names of the female sex, the other is to encourage individuals of that sex to use their bodies for sex work, surrogacy and acting in porn?
