Pedophiles don't abuse post pubescent teenage minors, they abuse babies and toddlers, so the abuse was not pedophilic in nature according to the reports. Pedophiles do not find sexually mature or maturing minors sexually attractive. To keep peddling this lie is insulting to the victims and your own intelligence.
If heterosexual men don't abuse boys then you have negated your own argument on availability as The availability of boys does not make homosexuals out of heterosexuals.
The church has been aware of this since the middle ages, probably long before then and it's reaction was not to protect the children but to protect itself. Blame the gay agenda, blame liberalism all you like but the fault is clearly with the institute that put it's own interests above it's stated mission.
