Any type of unrepentant ongoing sin ought to be a disqualifier to the priesthood, even if it's just lying to your wife about whether her favorite dress makes her look fat. Heterosexuals guilty of sexual sins have frequently been EJECTED from the priesthood, often even after public confession and repentance, but name two people known to actively engage in unrepentant sin yet nontheless accepted as priests. You're as welcome to your "personal" beliefs as anyone else, of course, but there is MILLENNIA of evidence that the myriad scriptural prohibitions of homosexuality should be taken literally, and it's hard for me to believe that the position the Holy Spirit consistently dictated up until about the time I was born was suddenly altered by the sexual revolution. God didn't change, society did, and while I don't insist on reading every part of the bible literally, in this case there's every reason to think we should against precious few suggesting otherwise. Reams and reams (maybe not the best choice of terms... ) of politically conscious (and often self serving) arguments against centuries of other arguments and Church practice don't really carry much weight with me, not when there are so many scriptural prohibitions and no such documentation to the contrary.

Ultimately what it boils down to is that all some change is devolution rather than evolution. The Church could be more inclusive if it made faith in God optional, too, but would it still be the Church if it did, or secular humanism with a cross over the door?
