If i told you to explain the historical context, inspirations and the elements of the Rococo art movement off hand and you got it wrong, should i snark at you for not being as "highly cultural", "educated and above other people" as me?
There's a major difference in knowing the complete ins and outs of a cultural subject, and having ever heard of it.
Particularly when we're discussing some of the most famous artists in Western society.
Do I expect you to know the complete disography of Bowie, or Michael Jackson, or the Beatles? No.
Do I expect you to have heard of them, or one of their songs? Yes.
Do I expect you to know the entire cast, crew and script of Star Wars, or The Godfather? No.
Do I expect you to have heard of it? Yes.
Do I expect you to know the entire works and inspirations of Picasso, or Van Gogh, or Da Vinci? No.
Do I expect you to have heard of them, or to know of one of their famous works? Yes.
It's baffling to me that a person born in the US, living in the 21st century, using the internet and being part of communities largely comprised of similar people upon the internet, has never heard of such a household name and pop-culture icon.
