It doesn't make sense and it shifts blame away from those who are truly responsible for the current crisis. If these pederasts had been kicked out of the priesthood when these incidents were first discovered (as they were in some dioceses) we wouldn't be staring down the barrel of RICO lawsuits.
Clarke also makes celibacy look like a fragile little flower which can't even be subjected to examination without all kinds of dire and unconnected consequences. That's just foolish.
