Having unnatural appetites is not a sin, but the way that you get unnatural appetites is through sin. A person isn't born an alcoholic. It happens through sustained self-abuse. Same with homoism. You're not born a homo. You become a homo by allowing yourself to accept evil into your soul. So if someone is a homo, and they don't act on it, they've still got a serious disorder which was self-inflicted. They are not suitable to minister to the people. I guess that when Francis said "who am I to judge [my own priests and clergy]", that he was trying to tell us that he doesn't have jurisdiction over the clergy. Hmm, is the pope a sedevacantist?
