I started a thread on the topic of this particular scandal, though not to do with celibacy. You might want a quick look.
My position on this is that the problem lies not with genuine clergy but the fact that the practises of the Catholic church leave it wide open to exploitation. I cite a particular testimony in the above thread that, in my mind, removes any possibility that the perpetrators were what anyone would describe as Christian above and beyond the general nature of the abuses.
The celibacy angle I didn't cover. My first reaction to this would be that since these schools and reformatories were practically rape dens, the description of 'celibate' seems rather inappropriate. I could see your point if the story described, say, a one-off rape charge of a celibate cleric, but the 'Irish holocaust' shows all the signs of being systematic. Vows of celibacy seem to have been abandoned a while ago.
Power, I fathom, is the driving force here, heightened by opaque practises.
