I read your first link. It refers to sexual abuse in the church and in schools over the last year or so. The comparison with the numbers in the Church’s report is not valid. I don’t think anybody doubts that there is much less sexual abuse in the Church in recent years and that when reported it is taken much more seriously than in the past.
That is, of course, at least partially due to the fact that the Church was starting from such a low level. It’s not difficult to be much better when you used to be really bad.
The Church’s own study reported 4.3% of priests accused of sexual abuse. Some of these were no doubt innocent, but then we can also assume some who were guilty were not accused.
100,000 priests and >6M teachers mean you would expect 60x as many teachers misbehaving with students. While I’m among the least happy people imaginable with the public school system, I don’t think there are anywhere near 1/4 million teachers misbehaving sexually with their underage students.
I read the whole report. See my post #33.
