In the old days, homosexuality was defined as an act, not something you felt. A woman being aroused by a photo does not a lesbian make.
If Homosexuality was still defined as an act, child molestation by priests, coaches, parents and pedophiles would have to be classified differently. They would be called properly, homosexual pedophiles. Of course in the case of heterosexual abuse, heterosexual pedophiles.
This could not be allowed, as the facts would be self explanatory.
