The choice is yours. To dismiss a very good book because of a review written by a third party or because it has an ancient symbol of healing (used by the Hebrew and not the inverted pentagram of witchcraft) is accepting ignorance as good and right.
It reminds me of when people were burning books that were written in German during WWII. A neighbor ran out yelling for them to stop. He picked up a book and held it in his hands and when they tried to forcefully put it in the fire he said - "it is the Bible" and the people realized what they had done.
All throughout His life Jesus taught us love and acceptance. That is the path I try to follow, the path that He laid out for us. I recommend that you educate yourself before you place judgement where God's judgement belongs.
Of all the attributes love is the greatest, for if a man has faith to move mountains, without love he is as nothing.
