I was looking through Amazon and saw this comment on a Noahide book, "Finding the God of Noah: The Spiritual Journey of a Baptist Minister from Christianity to the Laws of Noah":
Mr. Davis in his book praises Meir Kahane, the founder of the Jewish Defense League, who was in my opinion a pretty horrible person. That lowered his credibility with me to almost zero.
Contrary to the reviewer, it significantly raised my interest in the book...I'll post a review once I've received and read it.
