Only thing I disagree with is the thought that including the vulva as part of the vagina is the equivalent of a 13 yr old’s knowledge of sexual anatomy. Especially given that is how it is referred to in sex ed, by parents, teachers and the media. Huffington Post even did a whole piece on it

Sorry, the general public uses vagina for the vulva. You may not like it, you may wish people to have a better understanding of proper anatomical terms, but they don’t. Criticizing everyone who uses it that way is kind of stupid, especially when society as in general has decided otherwise.
