The importance is not on the age of the piece, but the popularity of it.

EVERY english-teaching school teaches about Shakespeare at some point, so you would be hard pressed to find an English-speaking adult who's never heard of the story of Romeo and Juliet. On the other hand, many people have never heard of Isaac Asimov, many people have never even read science fiction. I myself love science fiction and have read some Isaac Asimov, and still have never actually read most of his work. Do I deserve to Bichon spoilers for everything that I haven't ever read, just because I've never actually read it?

Fuck you, think about someone other than yourself for a change you sub-human filth
