BillDo has a post in which he plays down the Catholic priesthood’s image problem: Catholic League president Bill Donohue comments on the findings of the 2011 Annual Report on priestly sexual abuse that was released by the bishops’ conference; the survey was done by a Georgetown institute: The headlines should read, “Abuse Problem Near Zero… Continue reading Catholic Church 99 44/100% Pure
(Alternate title: “Numbers Mean Things”.) The increasingly-irrelevant Uncommon Descent blag had a post today, commenting on an article in Science News.
