"Forbidding men who have homosexual attractions (that may or may not have acted upon them before given themselves to God) seems hypocritical."
It's not. A man who suffers from same-sex attraction disorder is not competent to be a priest, nor is he suitable.
"but such a crime is not the inclination of every homosexual."
Actually, it is. Attraction to youth is one of the defining symptoms of SSAD.
"Shall we take one class of sinners and place the scapegoat of such scandals on a whole community?"
People who don't suffer from psychosexual disorders are capable of repenting and remaining chaste or celibate. Men who suffer from same-sex attraction disorder are not. It's not really their fault; they just can't.
There's no "scapegoating" going on. The simple fact is that mental disorders result in disordered thinking and disordered behavior, and such a man is not suitable for the priesthood until and unless he gets treatment and is cured of his disorder.
SSAD is curable, you know.
This is nonsense. Pure unadulterated nonsense. I would invite you to post your sources.
