Appeal to authority fallacy."This highly regarded and universally praisedbook by a professor of history from NC State about Kentucky does not fit my world view and hence I'm just going to ignore it"
Also appeal to popularity.
Also its not even that popular, and who cares if it was highly praised? You know what other books were highly praised?

Fifty Shades of Grey - Wikipedia, the free encyclopedia
Etc and so forth and so on.
