It isn't slander if it's true.
Invoking any reasoning that there there is, in fact, a segment of the Catholic clergy that is homosexual, and furthermore, that it is often covered up rather than being exposed and condemned by some of the church hierarchy, and furthermore, that many at least seem more outraged that the point is brought up than they are about the fact it often goes on for years rather than being condemned in a Christ-like fashion is likely to cause the following: Charges of church-bashing, violent arguments, vicious attacks on the messenger, and 1000+ threads that in the end devolve into arguments that are little better than "oh, yeah? So's your old man!" You have been warned. Proceed with caution. Your mileage may vary. Side effects may include outrage, a total loss of the sense of humor, grumbling, bloating, and a need to go have a nice lie down.
