To me it is the "controversial" books that ARE worth reading, including Mien Kampf. If we only read those things that raise no questions or set off alarms, we will never understand both sides of a story.
As for "elites"..I hate that word, it is always used as a pejorative, as if having attained expertise through hard work amounts to an unfair advantage.
I would like very much to read the book in question because it IS controversial.
