Thank you for supporting my point and ignoring the crux of the argument while you're busy trying to act like you know what a straw man is. How many best sellers could you name? A few dozen maybe? Out of how many thousands? Best seller is merely a term used by book dealers to determine popular books from others which aren't. Popularity and relevancy are not the same thing and you establish this by saying 'it'll be as relevant as any other best seller'.300,000,000 is merely the use of an unrealistic inflated number. That assumes that even infants could buy it, and a copy for each person in a family that might share a book. Totally ridiculous. Your point is irrelevant anyway, if it becomes a best seller it will be as relevant as any other best seller.
There are thousands of best selling books in EVERY genre from cooking to science fiction. These books have been bought by thousands and their popularity is unquestionable, the fact that they have been bought by droves does not establish any kind of relevancy. It establishes popularity.
Now to explain to you what a straw man is. I brought up the 300,000,000 figure in a related example(see Ralph Nader). I never stated that 300,000,000 people needed to buy Palin's book for it to become relevant. What I stated was that popularity does not equal to relevancy specially in a world where 'best sellers' number in the thousands and are subjectively defined by each independent dealer. Hopefully this explains to you what a straw man is.
