Oh, I agree. The point I was making is sin is sin. Aldultury is no less a sin than homosexuality. A lust in the heart is a lust in the heart.
Adultery is no less of a sin than sodomy with a member of the same sex.
But an adulterer does not claim that he is free of sin because adultery is his "orientation" (at least, not usually). All men, and all women, are adulterers in this sense.
Doing it, OTOH, is a major sin.
The modern invention of "orientation" towards same-sex acts tries to eliminate the distinction between a tendency towards sin (which we all share) and acting out one particular sin, in this case, sodomy.
