I really have a hard time believing conspiracy theories. I took a look at the bn.com web site. Liberal Facism is listed as #9 on their top 100 list. So no problem obtaining it from their web site.

Basic rule of government is to always look for incompetence before you look for conspiracy. I think the same applies here. A more likely explanation of shortages is that (a) some customers hide the book, and (b) the clerks don’t have a clue what’s in the store, regardless of politics.
