By "unfair," then, you mean "rhetorically effective." This personal attack of yours could be lodged against any incomplete account. Unless an article or a book deals exhaustively with a topic, you could say the author is being unfair to the readers for not giving the whole story.

Am I being unfair for assuming the readers of a publication about Christianity know what the Book of Revelation is?

How do I "not give the readers a chance to think" for themselves? Am I holding them hostage, preventing them from looking up references themselves?

Am I the one who tells Christians they should read the Bible as a single, unified book rather than as a library? If it's a book (inspired by its single, unifying author, God), it has a beginning, a middle, and an end. Revelation is at the end of the Bible. I didn't put it there, so you're shooting the messenger.

And you're calling me "unfair" with these red herrings and personal attacks? That's the pot calling the kettle black, I'm afraid.
