Query: why waste time to read garbage?

Apparently, the authors don't know anything about genetic:even basic theory of Genetic scinece, I wonder how they can write such a book on socilal management??? sure, this book is garbage, no doubt...full of unrealities..... Maybe because genetic engineer is so popular in present, many people want to touch it, but at least those people should have some basic knowledge.....too bad, such a bad book....., do not waste time on it....
