While we appreciate your opinions on the subject, the intent of customer reviews is to assist our customers in making an informed purchase decision. We provide our customer reviews section for you to comment on the merits of the book and the author’s writing style. We ask that you not use it as a place for discourse on the subject matter.
It could be that this is just a slip in a too-far automated submission review system, but if corporate policy would really lead Amazon to reject thoughtful book reviews because they include “personal opinions on the subject matter,” then Amazon has really lost its touch. A ban on opinionated reviews would take the very “We” out of media that made Amazon a hub in the first place.
