You're right, it's an imperfect analogy.

Let's say, instead: Barnes and Noble decides they only want to sell non-fiction books.

Sure, it's arbitrary, and it's probably bad business, but: it's their store.

Now, suppose you are a fiction writer.

Still going to throw that hissy fit?

> Barnes and Noble decides they only want to sell non-fiction books

No, a better analogy is if Barnes and Noble decides they only want to sell creationism books.

That's an excellent analogy. Those of us who prefer science based books would go elsewhere, while those who loved the comforting and protected "Creationist" environment would find a good home at B&N.

Science Based authors aren't owed a living by B&N, and would have to sell their books elsewhere.

On the other hand, you would have a corporation actively engaged in trying to mislead the public and stifle the truth.
