With respect, ma'am, that's not an "orientation". It's a temptation. Our sexuality is ordered, or oriented toward the other: men to women, women to men. I think you know this. Homosexual attractions are a disorientation, a perversion, a temptation to do what is inherently and irretrievably wrong. To simply call it another "orientation", as though it were no different morally from the orientation of men to women and women to men flies in the face of Sacred Scripture and Natural Law.
CCC paragraph 2358: The number of men and women who have deep-seated homosexual tendencies is not negligible. This inclination, which is objectively disordered, constitutes for most of them a trial.
The word "orientation" means, as you know, to be turned in a particular direction. The homosexual tendency is a matter of having an objectively disordered oientation.
