Is pseudoscience privileged over pseudohistory?

Ford’s Theater National Historic Site has banned removed from sale Bill O’Reilly’s book on the Lincoln assassination from its bookstore because the book is not historically accurate. Can it be any worse than Grand Canyon: A Different View, which is still on sale at the Grand Canyon National Park Bookstore?

According to a group called Public Employees for Environmental Responsibility, the book has been moved to an apparently ad hoc Inspirational section of the bookstore, and the National Park Service has delayed issuing instructions on how to deal with creationist questions.

Is pseudoscience based on religion somehow privileged over pseudohistory? Apparently, yes.
