If a religion condemns homosexuality.. And you are homosexual.. Why would you want to subscribe to that religion ?
Even more baffling to me, why would you want to be a preacher of that set of ideas ?
I'm not religious.. I prefer the religious institutions be allowed to be as bigoted as is their nature, they must be allowed to show their true colors, so that people can see them for what they are and avoid them more readily.
* that the life of a priest will cure them
* prevent them from having the opportunity for acting on their urges
* or at least that the righteous lifestyle makes up for their sinful thoughts
those people don't become priests despite being gay, they become priests because they are gay.
Your logic is strange, if they are completely faithless (like me!), then they see no moral wrong with them being as they are, and so, since they're doing nothing wrong, there is no need for "cover".
As for opportunity, are you suggesting that the prist-population contains an higher than average homosexual non-pedophile men ?
(I assume the pedophiles are not using the app since they have ample supply of choir boys?)
