I wonder just how Catholic this school is if it appealed to a homosexual couple. If the school were teaching sound doctrine, as few Catholic schools actually do, then I have a hard time seeing why it would appeal to a homo couple. Why would they send their "child" there only to be told daddy and daddy are living in sin? I would bet anything the school teaches watered down Catholicism, like the "catholic" schools I went to.
Add to this turmoil equal measures of fear, anxiety, guilt, remorse, pleasure, pain and it becomes a massive psychological problem.
The resulting homosexual adult is extremely contrary, due in great part to their unhappy and frustrating sexual confusion.
They want what they don't want; they have what they don't have. This malfunction of the normal maturation process into healthy adulthood causes endless conflict. They define themselves by the negative.
All homosexual adoption is child abuse. Nothing good will come from it.
