You haven't answered the question. That one can be harmful if acted on isn't a justification for it being a mental disorder. It's not about one being consenting and one not and we are not not debating about the wrongness of one versus the other so get your knickers out a knot.
I only get upset with stupidity from intelligent people so, you have no worries there mate. My knickers are barely rumpled.
I wasn't justifying anything. I'm not a psychologist and I'm not associated with whoever decides what is or isn't a disorder. I was giving you an answer to your question not a justification. It might help if you only actually asked questions when you were curious as to the answer rather than when you wanted to have a conversation you've already thought through in your head.
Personally I don't know that pedophilia is actually a disorder.
