Amazon.com Complaint - Amazon Products Ratings
It is unfortunate that Amazon does not pay more attention to reviewers who rate and review the books. There are some people with a political agenda who will rate a book One Star in order to downgrade the results, or vice-versa, rate 5 stars for the authors they support. I found someone who does just that and the website of this person is a group of people with a very strong political agenda.
Therefore, after finding this out I will not trust book (and other merchandise) review ratings given on Amazon, and will not shop there anymore.
