Liberals are always 'oh so concerned' that someone might want to 'sell' books. (While they publish the vast majority of books.)
If you disagree with a fact - state your disagreement.
Have you EVER heard that phrase about someone 'just wanting to sell books' used on a liberal? It was used against Linda Tripp - Paula Jones - and Jennifer Flowers. It was NEVER said about Clinton, Obama, or any other liberal...
Does that give you pause?
How many hundreds (or thousands) of times has the very same accusation been thrown at Sean Hannity by "conservatives" on this very site?
