The only argument she could give was the pathetic "you're a TERF". For starters when you have to jump to personal attacks that quickly it shows just how little knowledge you actually possess on the subject, not to mention TERF just means "someone who understands biology".
Back to "banned books" as a definition. There's lists of books that anything from a single library to national governments opt to say "no" those lists are honored by those who respect the source, but most of us know it's just a stupid list and go to another library or another country to get a book!
