(1) Per the John Jay study (below), only 96 of 4,329 (2.2%) offenders were truly pedophiles in the sense of targeting pre-pubescent children. The vast majority (about 80%) of offenders were in fact homosexuals.
(2) For specific testimony on the predation by homosexuals visited on seminarians and young priests, this recent CNA article on our very own Archdiocese of Newark is worth reading in detail:

(3) With regard to Bishop Morlino's letter, he has been quite explicit with his language. Quotes directly from his letter:
"It is time to admit that there is a homosexual subculture within the hierarchy of the Catholic Church that is wreaking great devastation in the vineyard of the Lord."
"...until recently the problems of the Church have been painted purely as problems of pedophilia — this despite clear evidence to the contrary."
"...in the specific situations at hand, we are talking about deviant sexual — almost exclusively homosexual — acts by clerics. We’re also talking about homosexual propositions and abuses against seminarians and young priests by powerful priests, bishops, and cardinals."
