They like reading books about birds? No, wait, that avian.
But seriously, let's say you only read 10 books in your life, because you live in a society where stories are more often told in film, or because you're 10 or whatever, and that book just blew your goddamned mind.
It's just not right to have some gatekeeper tell you that your opinion isn't valid because you don't read 50 books a month.
