"It's also not a motive for comfort to know that, according to sociological research, the percentage of priests guilty of these crimes is no higher than in other comparable professional categories. In any event, one must not stubbornly present this deviance as if it were a nastiness specific to Catholicism."
He was not saying this to minimize the effect on survivors or to deny the gravity of clergy abuse, but rather to point out that the Church is not the sole organization where sexual abuse exists. I'm not a professional media analyst, but it seems like the vast majority of media coverage of sexual abuse has to do with clergy abuse and does not reflect the actual breakdown of where sexual abuse tends to happen. Abuse at the hands of clergy is particularly evil because it is using one's position as a spiritual leader to manipulate and abuse those who are vulnerable. However, there are also other religious groups who have issues with sexual abuse among their clergy along with doctors who perform this, coaches, teachers and other carer/mentor type figures who abuse the roles they perform in peoples' lives in order to hurt others. I don't think the pope emeritus was trying to deny that this is indeed wrong.
