It's just that you don't read about it in the news.
At this point, many of the 'long submerged' cases of abuse are either trial lawyers looking for a payday because the alleged perp is dead and can't defend himself, or folks with some mental/emotional problems (it is less and less believable as time goes on that these folks were 'afraid to come forward'). Unfortunately the ambulance chasers and the drama seekers tend to 'pile on' to notorious cases. This of course makes it harder for an actual victim to get help or prove his case . . . . but that is often true of stories that get big news time.
I researched this issue very carefully when we started looking for a new church home, because we did not want to jump from the frying pan into the fire. The abuse was largely confined to a relatively small number of dioceses, which were mostly headed by heterodox bishops who were busy undermining the Church in the name of "modernity" and "relevance" and "the spirit of Vatican II" (if they had stuck to the Church's teachings and policies on homosexual offenders, there never would have been a serious problem.)
“Oh, no, the Episcopal scandals are already here, and have been for some time. They are just being swept under the rug by a complaisant media. I know, because I used to be an Episcopalian. Our (former) local cathedral is well known as a “meat market”, I am sorry to say.”
Yes, we have an Episcopal “church” here, next to the entertainment district, that is a well known hookup spot. Every Friday evening they have an after work dinner, and it’s known as one of the places you can find a new boyfriend for the evening, and then go out to the gay nightclubs.
