FAQ: vagina vs vulva and public “faces of feminism”

Q: A celebrity feminist said something about the incorrect usage of vagina vs vulva and I want you to explain every nuance of her thoughts to me and why feminism thinks that way.

Possibly her opinion is highly unpopular.
Also, just a thought, possibly she didn’t actually say quite what you think she said?
