A very poorly researched book that appears to exist solely to pander to elderly conservatives. It would take an entire essay to debunk all the historical inaccuracies. .
More worryingly, Ms. Southern concludes her section on Islam by stating that, and I quote, 'the crusades did nothing wrong.' The crusades, of course, lead to the massacre of the entire Jewish population of Jerusalem and the deaths of countless 'heretical' Eastern Christians at the hands of the crusader fanatics. I don't believe that Ms. Southern is celebrating the death of Jews, and thus I am inclined to attribute this to her lack of research.
I would not recommend this book to anyone looking for a factual, unbiased, or nuanced view of the current political and social climate.
