I think you're on to something. However, they all really do fit into one category. Specifically, sexual deviancy.
The human biological machine has an apetite for sex, just like it has an apetite for food. Without those God given apetites, the human race would perish. When the apetite get's screwed up, the machine dies, or dies off. For example, if you get a craving for anti-freeze and you just have to quench it - Well, you will be expiring quite soon. It is a deviency of sorts and not natural. It actually short circuits the whole reason for the apetite for food, to sustain the body.
Sexual deviancy is the same. It short circuits the whole purpose of the sexual apetite to begin with. The purpose is procreation. If God had not designed into men and women a strong desire to do what they do to make babies, man would have long since become extinct. When this desire gets messed up, you end up with people who are attracted to vegetables, animals, their own sex, tailpipes or a miriad of other activities that, no matter how vigorously practiced, cannot possibly conceive another human soul.
Same sex attraction is a deviancy and, yes, it is an apetite that can be aquired. That is why our children must be protected from this form of mental illness and deviant (not to mention physically dangerous) activity.
Calling it immoral and unacceptable is a good start...
