I agree, you shouldn't expect people to understand every reference you make. My statement was more about how the quote in the pic and, to a much lesser extent, the comment above both seem to view being introduced to a new thing by someone you like as sort of a bad thing. The quote in the photo especially is a red flag of not caring about the things the people you care about are into.

Obviously not everybody is going to be familiar with the same media as you. But if somebody gets upset with you because you quoted a joke from a source that they're unfamiliar with, that's on them, not you.
