Honestly, I do not know.
Never in my catholic upbringing in the 50's,60's and into the 70's have I ever seen this kind of abuse.
Granted, I had nuns, coaches and priests beat the c...p out of me for not following the rules, but, if anyone of those nuns, coaches or priests ever heard that I was sexual abused, then they would have made sure that the offender would never have the ability to hurt another child/person.
They were trying to mold my character,and they did. -( for better, or worse )- Years after I graduated High School I just happened to meet Sister Helen, again.
We had a great discussion.
I almost got expelled from HS two weeks before graduation because of an "academic" discussion between the two of us.
I won the debate, decided by the Principle of the school.
Long story shortened, she told me I was the favorite student she had ever taught.
I always held a grudge against this nun, until that moment.
In the fullness of time, I learned that I was surrounded by discipline, support and love.
