In the county where I live, which has a declining urban city at its core, half of children born are out-of-wedlock. In the urban core itself, 70 percent are born out of wedlock, and among African-Americans, 90 percent, per the county Health Department. I have never heard of a single Catholic priest fathering any of these children. If you want to attack the problem of out-of-wedlock fathering, you are looking in the wrong place. If you want to encourage hate of the Catholic Church, I guess you're onto something. 
As an aside, I note that the vicious types who are raising this issue have resumed calling children "illegitimate," -- (only those fathered by priests, of course) -- as if it were their fault. Amidst the mad frenzy of throwing mud at the Catholic Church, could the heathens at least refrain from that? Just a small request in the interest of "civility."
