Comment by Eliezer Yudkowsky - I may never actually use this in a story, but in another universe I had thought of having a character mention that... call it the forces of magic with normative dimension... had evaluated one pedophile who had known his desires were harmful to innocents and never acted...
"As always, pedophilia is not the same as ephebophilia."
That's correct, but as we all know, people don't say things that are true just because they are true. Otherwise we would be walking around quoting Wikipedia at random for most of the day.
We actually say things because we want to do something.
Edit: Ok now I actually read what he wrote and it makes no sense
