As far as I know, Rabbi Boteach is a proper, orthodox Jew who works in the world-at-large.
Merely having that name in the book title is not necessarily an indictment of R’ Boteach, who does a great deal of chessed to all kinds of people, and from what I hear from gentiles in the workplace, he is making a kiddish Hashem. They like him and like the ideas he brings across.
As far as I am concerned, let him be Shmuely.
I have not read the book so I dont know the context of it. I won’t read the book either; not that interested.
