Query: Poor source for understanding this controversial subject

It is a shame Brian Morris missed an opportunity to analyze and expose the lack of unbias objectivity in almost all the papers written on the topic of circumcision. Almost every source referenced in his book is slanted somewhat by the authors of the study. Too many of his references have conclusions that are not supported by the data presented in the paper. It is a shame he didn't bring this to light in his narrative. Probably he wanted to continue the myths that the medical community wants to protect to allow for their continued financial rewards for doing unnecessary surgeries.
